Vaadin Table - header and row column width sometimes don't match

Question

Originally by sseppola

Sometimes the border between two columns in the table is not drawn in the same x-position in table header as in table rows. There seems to be a 1px mismatch that can be reproduced both with Valo and Reindeer themes.

How to reproduce?

1. Open Valo theme demo > tables
2. Select "hierarchical"
3. Minimize the 1st column by dragging the border as far left as possible

You will notice that the mismatch occur exactly when the border is drawn to its ultimate left position.

This error can also be reproduced by using the "expandratio" for one column in the table
