This is about as much as I can reveal. I have inserted an image and some example code.
Notice that the 'User Name' header does not align with the rows. On load (initially), the header and row data lays out properly. But when I try to resize the 'user name' or header columns, then they never realign with the grid data.
Ironically, if I click the 'link' that refreshes this grid panel, the columns line up and work correctly.
There is a lot of other calling class code which I can't reveal but it is essentially this:
I attached the rest of the code.
VerticalPanel panel = new VerticalPanel();
