I am using row colorization in our of our table reports. So, can we show a legend at the top of the report to just giving an information about the color we using? (As we use some icons for Project condition).
You may have to just describe what you have highlighted in the description box of the report. If you have preserved an old dashboard in your database's pages section, you can make an old style dashboard with an HTML text header that you can code. Then embed your report in that old style dashboard. We haven't come to a place yet where the table page is format-able. Danimal may be able to provide you one of his hacks.
