Bug 147676 [regression]Visibility set in the first col will affect the second col
Description: Visibility set in the first col will affect the second col Steps to reproduce: 1. Insert a grid(3*3), insert contents to each cell. 2.Set the first col to hide all in visibility and preview Expected result: Only the first col is hidden. Actual result: The second col is hidden, too. If you set the second col in step2, the third col will disappear.
