Gets or sets whether row and column headers are visible on the worksheet.
The image below shows the appearance of the worksheet when row and column headers are shown, and when row and column headers are hidden (the workbook is opened in Microsoft® Excel®).
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.
