Coloring cell background in JFace tables [message #193316]

The author of the following describes how to set the background color of a
row in a table using an undocumented feature in the JFace table viewer
(thank you for provding this!).

In a nutshell, you implement both ITableLabelProvider AND IColorProvider
in your label provider class. IColorProvider has you implement
getBackground and getForeground methods. They don't know which column it
is, so with these you affect an entire row.

Can anyone describe how to do this for a single cell?

We've tried but have been unable to make an image on the fly in
getColumnImage(). Can anyone provide a snippet of code that does this?

Questions to jFace classes should be asked on the eclipse.platform newsgroup.

To color individual cells, use an ITableColorProvider.
