Adding a background colour to a row or column is a good way of emphasising it. Background colours are also added using either the style editor or the effects command.
To add a background colour to a table style:
The selected cells will appear in the new colour.
Create a new style based on your existing table style. Call it something like Table colour.
Go to the Colour section of the Style dialogue box.
Turn on Background colour. Choose the colour you want for the background, either by using the colour selector, or by typing in RGB values, or by clicking on one of the pre-defined colour buttons in the palette.
Click OK.
Select the part of the table you want to appear in the new colour, and apply the Table colour style to it.
