Remarks

Use this property to specify the number of columns used for the row header.

The minimum value you can set is 1. The maximum value you can set is 255.

When you set this property to a value greater than 1, additional columns are added to the row header.

This property does not have an effect unless the RowHeader.Visible property is set to true.

Set the ColumnHeader object's ColumnHeader.RowCount property to specify the number of rows to display as the column header.

Example
This example sets the row header to have three columns and to display the letters in the second of the three columns in the row header.
FarPoint.Web.Spread.RowHeader rhdr;
rhdr = FpSpread1.ActiveSheetView.RowHeader;
rhdr.ColumnCount = 3;                                              //  row header has three columns
rhdr.AutoText = FarPoint.Web.Spread.HeaderAutoText.Letters;        //  row header displays letters
rhdr.AutoTextIndex = 1;                                            //  automatic text in second zero-index row
Dim rhdr As FarPoint.Web.Spread.RowHeader
rhdr = FpSpread1.ActiveSheetView.RowHeader
rhdr.ColumnCount = 3                                              ' row header has three columns
rhdr.AutoText = FarPoint.Web.Spread.HeaderAutoText.Letters        ' row header displays letters
rhdr.AutoTextIndex = 1                                            ' automatic text in second zero-index row
