Summary:
changelog: Improved column widths in data tables
This diff fixes two issues:
1) dynamic width columns became invisible if there is too much else, and therefor it was hard to make them bigger or even notice them
2) column headers could be out of sync with the actually rendered rows, due to minor styling differences
