How to: Show and Hide Row and Column Headings
Cells in a worksheet are arranged in rows (Worksheet.Rows) and columns (Worksheet.Columns). Each row and column has a unique name (rows use numbers “1”, “2”, “3”,…, “1048576”, and columns use letters “A”, “B”, “C”,…,”XFD”). Row and column names are displayed on a worksheet’s left and top side, respectively. Use the Worksheet.ActiveView.ShowHeadings (WorksheetView.ShowHeadings) property to control row and column headings’ visibility in a worksheet.
Use the WorksheetPrintOptions.PrintHeadings property to specify whether row and column headings should appear in a printout. Refer to the How to: Specify Print Settings document for details on how to specify print options for a worksheet.
// Hide row and column headings in the first worksheet. workbook.Worksheets.ActiveView.ShowHeadings = false;
