Remarks

When saving a workbook by this mode, StartSheet will be checked when saving every worksheet in the workbook. For one sheet, if StartSheet gives true, then all data and properties of rows/cells of this sheet to be saved will be provided by the implementation of this interface. In the first place, NextRow will be called to get the next row index to be saved. If a valid row index is returned(the row index must be in ascending order for the rows to be saved), then a Row object representing this row will be provided for implementation to set its properties by StartRow. For one row, NextCell will be checked firstly. If a valid column index be returned(the column index must be in ascending order for all cells of one row to be saved), then a Cell object representing this cell will be provided for implementation to set its data and properties by StartCell. After data of this cell is set, this cell will be saved directly to the generated spreadsheet file and the next cell will be checked and processed.
