Wt

Affected: Wt 4.12.5 (and former versions, checked down to 4.11.4)

WTableView with fixed first column, i.e. setRowHeaderCount(1).
setColumnWidth updates the header cell only but not the data cells.
Then a manual resize of the first columns causes a gap after the fixed first column.

Workaround: setColumnWidth for a not fixed column updates the whole fixed first column.

Until 4.12.2, even a scheduled setColumnWidth(0, w) reproduced the bug.
Since 4.12.3, only pushing the button "Set C0 width" might reproduce this bug depending on the window size. Though, the WTableView has double scrollbars and the first column is scrolled weirdly (refer to Bug #14066: WTableView: Fixed first column is not scrolled if no header row since 4.12.2).
