Description

Hello,

I have added a colspan functionality which seems to work fine in all cases until 4.6.2. From 4.6.3 css seems to break column span functionality.

Here is a sample plunker i have added.

In plunker if you change

to anything greater than 4.6.2 column headers seems to be hidden.

Any help appreciated.

Research direction
The issue reports that column span (colspan) broke in ui grid version 4.6.3+ compared to 4.6.2, with column headers hidden. The provided Plunker demonstrates the problem. Research should compare the CSS changes between versions, focusing on ui grid.css, especially styles affecting column headers and colspan. Look at the release diffs or git history between 4.6.2 and 4.6.3 to identify the CSS rule that caused the regression. The fix likely involves adjusting or reverting a specific CSS property that hides column headers when colspan is used.
