I would like to dynamically set cell border properties in cross-tab, based on cell content.
For example: if cell value is negative - set border colour to red, or if cell value exceeds a limit - set cell border lines to thick yellow, or if cell value is null - remove border lines. A bit similar to conditional formatting in Excel... I saw highlighting function in BIRT, but there is no option to control frames.
This should be possible in BIRT with Java Script, but I could not find any working example

. I guess the code could be executed from conditional expression attached to cell.
Is this something feasible or I am trying to re-invent the wheel?
