    public class Cell 
    extends CompositeNode

Represents a table cell.

Cell can only be a child of a Row.

Cell can contain block-level nodes Paragraph and Table.

A minimal valid cell needs to have at least one Paragraph.

Example:

Shows how to create a table.
Document doc = new Document();
Table table = new Table(doc);
doc.getFirstSection().getBody().appendChild(table);

// Tables contain rows, which contain cells, which may have paragraphs
// with typical elements such as runs, shapes, and even other tables.
// Calling the "EnsureMinimum" method on a table will ensure that
// the table has at least one row, cell, and paragraph.
Row firstRow = new Row(doc);
table.appendChild(firstRow);

Cell firstCell = new Cell(doc);
firstRow.appendChild(firstCell);

Paragraph paragraph = new Paragraph(doc);
firstCell.appendChild(paragraph);

// Add text to the first call in the first row of the table.
Run run = new Run(doc, "Hello world!");
paragraph.appendChild(run);

doc.save(getArtifactsDir() + "Table.CreateTable.docx");

Example:

Shows how to iterate through all tables in the document and print the contents of each cell.
Document doc = new Document(getMyDir() + "Tables.docx");
TableCollection tables = doc.getFirstSection().getBody().getTables();

Assert.assertEquals(2, tables.toArray().length);

for (int i = 0; i < tables.getCount(); i++) {
    System.out.println(MessageFormat.format("Start of Table {0}", i));

    RowCollection rows = tables.get(i).getRows();

    for (int j = 0; j < rows.getCount(); j++) {
        System.out.println(MessageFormat.format("\tStart of Row {0}", j));

        CellCollection cells = rows.get(j).getCells();

        for (int k = 0; k < cells.getCount(); k++) {
            String cellText = cells.get(k).toString(SaveFormat.TEXT).trim();
            System.out.println(MessageFormat.format("\t\tContents of Cell:{0} = \"{1}\"", k, cellText));
        }

        System.out.println(MessageFormat.format("\tEnd of Row {0}", j));
    }

    System.out.println(MessageFormat.format("End of Table {0}\n", i));
}

Example:

Shows how to build a nested table without using a document builder.
public void createNestedTable() throws Exception {
    Document doc = new Document();

    // Create the outer table with three rows and four columns, and then add it to the document.
    Table outerTable = createTable(doc, 3, 4, "Outer Table");
    doc.getFirstSection().getBody().appendChild(outerTable);

    // Create another table with two rows and two columns and then insert it into the first table's first cell.
    Table innerTable = createTable(doc, 2, 2, "Inner Table");
    outerTable.getFirstRow().getFirstCell().appendChild(innerTable);

    doc.save(getArtifactsDir() + "Table.CreateNestedTable.docx");
}

 * Creates a new table in the document with the given dimensions and text in each cell.
 */
private Table createTable(final Document doc, final int rowCount, final int cellCount, final String cellText) throws Exception {

    • Property Getters/Setters Detail

      • getCellFormat

        public CellFormat getCellFormat()
        
        Provides access to the formatting properties of the cell.

        Example:

        Shows how to modify formatting of a table cell.
        Document doc = new Document(getMyDir() + "Tables.docx");
        Table table = doc.getFirstSection().getBody().getTables().get(0);
        Cell firstCell = table.getFirstRow().getFirstCell();
        
        // Use a cell's "CellFormat" property to set formatting that modifies the appearance of that cell.
        firstCell.getCellFormat().setWidth(30.0);
        firstCell.getCellFormat().setOrientation(TextOrientation.DOWNWARD);
        firstCell.getCellFormat().getShading().setForegroundPatternColor(Color.GREEN);
        
        doc.save(getArtifactsDir() + "Table.CellFormat.docx");

        Example:

        Shows how to combine the rows from two tables into one.
        Document doc = new Document(getMyDir() + "Tables.docx");
        
        // Below are two ways of getting a table from a document.
        // 1 -  From the "Tables" collection of a Body node:
        Table firstTable = doc.getFirstSection().getBody().getTables().get(0);
        
        // 2 -  Using the "GetChild" method:
        Table secondTable = (Table) doc.getChild(NodeType.TABLE, 1, true);
        
        // Append all rows from the current table to the next.
        while (secondTable.hasChildNodes())

        // Remove the empty table container.
        secondTable.remove();
        
        doc.save(getArtifactsDir() + "Table.CombineTables.docx");

        Example:

        Shows how to modify the format of rows and cells in a table.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

      • getChildNodes

        public NodeCollection getChildNodes()
        
        Gets all immediate child nodes of this node.

        Note, ChildNodes is equivalent to calling GetChildNodes(NodeType.Any, false) and creates and returns a new collection every time it is accessed.

        If there are no child nodes, this property returns an empty collection.

        Example:

      • getCount

        public int getCount()
        
        Gets the number of immediate children of this node.

        Example:

        Shows how to add, update and delete child nodes in a CompositeNode's collection of children.
        Document doc = new Document();
        
        // An empty document, by default, has one paragraph.
        Assert.assertEquals(1, doc.getFirstSection().getBody().getParagraphs().getCount());

      • getCustomNodeId/setCustomNodeId

        public int getCustomNodeId() / public void setCustomNodeId(int value)
        
        Specifies custom node identifier.

        Default is zero.

        This identifier can be set and used arbitrarily. For example, as a key to get external data.

        Important note, specified value is not saved to an output file and exists only during the node lifetime.

        Example:

        Shows how to traverse through a composite node's collection of child nodes.

      • getDocument

        public DocumentBase getDocument()
        
        Gets the document to which this node belongs.

        The node always belongs to a document even if it has just been created and not yet added to the tree, or if it has been removed from the tree.

        Example:

        Shows how to create a node and set its owning document.
        Document doc = new Document();
        Paragraph para = new Paragraph(doc);
        para.appendChild(new Run(doc, "Hello world!"));

        Assert.assertEquals("Hello world!", doc.getText().trim());
      • getFirstChild

        public Node getFirstChild()
        
        Gets the first child of the node. If there is no first child node, a null is returned.

        Example:

        Shows how to use a node's NextSibling property to enumerate through its immediate children.
        Document doc = new Document(getMyDir() + "Paragraphs.docx");
        
        for (Node node = doc.getFirstSection().getBody().getFirstChild(); node != null; node = node.getNextSibling()) {

        public boolean accept(DocumentVisitor visitor)
                      throws java.lang.Exception
        Accepts a visitor.

        Enumerates over this node and all of its children. Each node calls a corresponding method on DocumentVisitor.

        For more info see the Visitor design pattern.

        Calls DocumentVisitor.VisitCellStart, then calls Accept for all child nodes of the section and calls DocumentVisitor.VisitCellEnd at the end.
        Parameters:

      • appendChild

        public Node appendChild(Node newChild)
        Adds the specified node to the end of the list of child nodes for this node.

        If the newChild is already in the tree, it is first removed.

        If the node being inserted was created from another document, you should use DocumentBase.importNode(com.aspose.words.Node,boolean,int) to import the node to the current document. The imported node can then be inserted into the current document.

        Parameters:
        newChild - The node to add.
        Returns:
        The node added.

        Example:

        Shows how to construct an Aspose.Words document by hand.
        Document doc = new Document();
        
        // A blank document contains one section, one body and one paragraph.
        // Call the "RemoveAllChildren" method to remove all those nodes,
        // and end up with a document node with no children.
        doc.removeAllChildren();
        
        // This document now has no composite child nodes that we can add content to.
        // If we wish to edit it, we will need to repopulate its node collection.
        // First, create a new section, and then append it as a child to the root document node.
        Section section = new Section(doc);
        doc.appendChild(section);
        
        // Set some page setup properties for the section.
        section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
        section.getPageSetup().setPaperSize(PaperSize.LETTER);
        
        // A section needs a body, which will contain and display all its contents
        // on the page between the section's header and footer.
        Body body = new Body(doc);
        section.appendChild(body);
        
        // Create a paragraph, set some formatting properties, and then append it as a child to the body.
        Paragraph para = new Paragraph(doc);
        
        para.getParagraphFormat().setStyleName("Heading 1");
        para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);
        
        body.appendChild(para);
        
        // Finally, add some content to do the document. Create a run,
        // set its appearance and contents, and then append it as a child to the paragraph.
        Run run = new Run(doc);
        run.setText("Hello World!");
        run.getFont().setColor(Color.RED);
        para.appendChild(run);
        
        Assert.assertEquals("Hello World!", doc.getText().trim());
        
        doc.save(getArtifactsDir() + "Section.CreateManually.docx");
      • deepClone

        public Node deepClone(boolean isCloneChildren)
        Creates a duplicate of the node.

        This method serves as a copy constructor for nodes. The cloned node has no parent, but belongs to the same document as the original node.

        This method always performs a deep copy of the node. The isCloneChildren parameter specifies whether to perform copy all child nodes as well.

        Parameters:
        isCloneChildren - True to recursively clone the subtree under the specified node; false to clone only the node itself.
        Returns:
        The cloned node.

        Example:

        Shows how to clone a composite node.
        Document doc = new Document();
        Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
        para.appendChild(new Run(doc, "Hello world!"));
        
        // Below are two ways of cloning a composite node.
        // 1 -  Create a clone of a node, and create a clone of each of its child nodes as well.
        Node cloneWithChildren = para.deepClone(true);
        
        Assert.assertTrue(((CompositeNode) cloneWithChildren).hasChildNodes());
        Assert.assertEquals("Hello world!", cloneWithChildren.getText().trim());
        
        // 2 -  Create a clone of a node just by itself without any children.
        Node cloneWithoutChildren = para.deepClone(false);
        
        Assert.assertFalse(((CompositeNode) cloneWithoutChildren).hasChildNodes());
        Assert.assertEquals("", cloneWithoutChildren.getText().trim());
      • ensureMinimum

        public void ensureMinimum()
        If the last child is not a paragraph, creates and appends one empty paragraph.

        Example:

        Shows how to ensure a cell node contains the nodes we need to begin adding content to it.
        Document doc = new Document();
        Table table = new Table(doc);
        doc.getFirstSection().getBody().appendChild(table);
        Row row = new Row(doc);
        table.appendChild(row);
        Cell cell = new Cell(doc);
        row.appendChild(cell);
        
        // Cells may contain paragraphs with typical elements such as runs, shapes, and even other tables.
        // Our new cell does not have any paragraphs, and we cannot add contents such as run and shape nodes to it until it does.
        Assert.assertEquals(0, cell.getChildNodes(NodeType.ANY, true).getCount());
        
        // Calling the "EnsureMinimum" method on a cell will ensure that
        // the cell has at least one empty paragraph, which we can then add contents to.
        cell.ensureMinimum();
        cell.getFirstParagraph().appendChild(new Run(doc, "Hello world!"));
      • getAncestor

        public CompositeNode getAncestor(int ancestorType)
        Gets the first ancestor of the specified NodeType.
        Parameters:
        ancestorType - A NodeType value. The node type of the ancestor to retrieve.
        Returns:
        The ancestor of the specified type or null if no ancestor of this type was found.

      • getChild

        public Node getChild(int nodeType, int index, boolean isDeep)
        Returns an Nth child node that matches the specified type.

        If index is out of range, a null is returned.

        Note that markup nodes (NodeType.STRUCTURED_DOCUMENT_TAG and NodeType.SMART_TAG) are traversed even when isDeep = false and GetChild is invoked for non-markup node type. For example if the first run in a para is wrapped in a StructuredDocumentTag, it will still be returned by GetChild(NodeType.Run, 0, false).
        Parameters:
        nodeType - A NodeType value. Specifies the type of the child node.
        index - Zero based index of the child node to select. Negative indexes are also allowed and indicate access from the end, that is -1 means the last node.
        isDeep - True to select from all child nodes recursively. False to select only among immediate children. See remarks for more info.
        Returns:
        The child node that matches the criteria or null if no matching node is found.

        Example:

        Shows how to traverse through a composite node's collection of child nodes.
        Document doc = new Document();

      • getChildNodes

        public NodeCollection getChildNodes(int nodeType, boolean isDeep)
        Returns a live collection of child nodes that match the specified type.

        The collection of nodes returned by this method is always live.

        A live collection is always in sync with the document. For example, if you selected all sections in a document and enumerate through the collection deleting the sections, the section is removed from the collection immediately when it is removed from the document.

        Parameters:
        nodeType - A NodeType value. Specifies the type of nodes to select.
        isDeep - True to select from all child nodes recursively. False to select only among immediate children.
        Returns:
        A live collection of child nodes of the specified type.

      • insertAfter

        public Node insertAfter(Node newChild, Node refChild)
        Inserts the specified node immediately after the specified reference node.

        If refChild is null, inserts newChild at the beginning of the list of child nodes.

        If the newChild is already in the tree, it is first removed.

        If the node being inserted was created from another document, you should use DocumentBase.importNode(com.aspose.words.Node,boolean,int) to import the node to the current document. The imported node can then be inserted into the current document.

        Parameters:

        Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.

        Parameters:
        xpath - The XPath expression.
        Returns:
        The first Node that matches the XPath query or null if no matching node is found.

        Example:

        Shows how to select certain nodes by using an XPath expression.
        Document doc = new Document(getMyDir() + "Tables.docx");
        
        // This expression will extract all paragraph nodes,
        // which are descendants of any table node in the document.
        NodeList nodeList = doc.selectNodes("//Table//Paragraph");
        
        // Iterate through the list with an enumerator and print the contents of every paragraph in each cell of the table.
        int index = 0;
        
        Iterator<Node> e = nodeList.iterator();
        while (e.hasNext()) {
            Node currentNode = e.next();
            System.out.println(MessageFormat.format("Table paragraph index {0}, contents: \"{1}\"", index++, currentNode.getText().trim()));
        }
        
        // This expression will select any paragraphs that are direct children of any Body node in the document.
        nodeList = doc.selectNodes("//Body/Paragraph");
        
        // We can treat the list as an array.
        Assert.assertEquals(nodeList.toArray().length, 4);
        
        // Use SelectSingleNode to select the first result of the same expression as above.
        Node node = doc.selectSingleNode("//Body/Paragraph");
        
        Assert.assertEquals(Paragraph.class, node.getClass());
      • toString

        public java.lang.String toString(SaveOptions saveOptions)
                       throws java.lang.Exception
        Exports the content of the node into a string using the specified save options.
        Parameters:
        saveOptions - Specifies the options that control how the node is saved.
        Returns:
        The content of the node in the specified format.

      • toString

        public java.lang.String toString(int saveFormat)
                       throws java.lang.Exception
        Exports the content of the node into a string in the specified format.
        Returns:
        The content of the node in the specified format.
        Parameters:
        saveFormat - A SaveFormat value.

        Example:

        Shows how to extract the list labels of all paragraphs that are list items.

                System.out.println("\tList label combined with text: {label.LabelString} {paragraphText}");
            }

        Example:

        Exports the content of a node to String in HTML format.
        Document doc = new Document(getMyDir() + "Document.docx");
        
        Node node = doc.getLastSection().getBody().getLastParagraph();

        Example:

        Shows the difference between calling the GetText and ToString methods on a node.
        Document doc = new Document();
        
        DocumentBuilder builder = new DocumentBuilder(doc);
        builder.insertField("MERGEFIELD Field");
