I was doing things the hard way, setting HTML codes in each cell for bold. Now I found setRowTextBold(), and the other methods. Duh on my part.
Could you add: setCellImage(row,id,image)
to put a small image first thing in the cell, then the text? Not as a background image, though.
A good example would be like in an email program, the envelopes for new, read, replied, etc.
And not have it affect sorting like setRowTextBold() and setRowTextStyle() don’t.
I was using a separate column for the image, but it is too wide. It would be nice if the ‘img’ column types didn’t have as much padding. To show a 16x16 image, like a checkmark, needs 37px wide to make it look centered and good (even padding on both sides). Way too much wasted space. But, I know it probably is the same css tag for all the headers.
