While I'd like to keep by default the current behaviour of column widths of text tables, it would be nice to also have the option to:
1. Fix the width of each column individually
2. Add a "Fit to content" option
In many cases, I design my dashboards so that I have sufficient screen real estate and do not need to "shrink" my text tables. In this case, the current behaviour works well.
But in those cases where I do need to display quite a lot of columns, being able to reduce the width of the ones containing less characters (ex: single digit integer with short alias name) would make my dashboard a lot clearer.
