The gridlines in an Excel spreadsheet are only visible when looking at the worksheet electronically, and are not displayed when you send a worksheet to a printer.
However, sometimes you might want to hide gridlines in an Excel worksheet when it is viewed on a computer screen. Two different ways of doing this are described below.
The visibility of the gridlines in an Excel worksheet is controlled by the Gridlines option, which is switched on by default.
A second way to hide gridlines in Excel is to color the cell backgrounds in white. This method can be used to hide the gridlines in a chosen range of cells, or for an entire worksheet.
To color the cell background:
Click the down arrow at the side of the Fill Color button , which is located on the 'Home' tab of the Excel ribbon (or on the formatting toolbar in Excel 2003).This gives you a selection of colors that you can use to fill the background of the selected cells (see above right). If you select white as the fill color, this will give the appearance of simply removing the gridlines in the selected cells of your worksheet.
