Formatting the cell borders
To quickly choose a line style and color for the borders of a cell, click the small arrows next to the Line Style and Line Color icons on the Formatting toolbar. In each case, a palette of choices is displayed.
For more control, including the spacing between the cell borders and the text, use the Borders tab of the Format Cells dialog. There you can also define a shadow. See Chapter 10 for details.
|| The cell border properties apply to a cell, and can only be changed if you are editing that cell. For example, if cell C3 has a top border (which would be equivalent visually to a bottom border on C2), that border can only be removed by selecting C3. It cannot be removed in C2.
