How to: Show or Hide a Row or Column
You can also hide a row or column in a worksheet by setting the row height (Row.Height) or column width (Column.Width, Column.WidthInCharacters or Column.WidthInPixels) to 0, respectively (see the How to: Specify Row Height or Column Width document).
Worksheet worksheet = workbook.Worksheets; // Hide the 8th row of the worksheet. worksheet.Rows.Visible = false; // Hide the 4th column of the worksheet. worksheet.Columns.Visible = false;
The image below shows how to hide and unhide worksheet rows and columns via the SpreadsheetControl user interface.
