Text overflowed canvas as tables didn't calculate correctly the width of their columns. They used the whole table width available for each column. Also, the `cell` parameter was wrongly parsed if used with its optional argument (expand ratio). This PR fixs the parsing of `cell` parameter (i.e. `cell=e`) and the distribution of the full table width between columns, but it overrides automatically the `expand` flag if the column is smaller than it could be, to allow a better UX out-of-the-box. It keeps the `expand_ratio` flag to let the user customize how every column grows in relation to the rest. Partially fix #6289.
