You do not normally need to call this method as cell and table widths are maintained automatically. You can call this method before exporting to PDF (or any other fixed-page format), only in rare cases where you confirmed that tables appear incorrectly laid out in the output document. Calling this method might help to correct the output.
[C#] Document doc = new Document(MyDir + "Document.doc"); // Normally this method is not necessary to call, as cell and table widths are maintained automatically. // This method may need to be called when exporting to PDF in rare cases when the table layout appears // incorrectly in the rendered output. doc.UpdateTableLayout();
