Browser, word properties not fully displayed, table columns too narrow

Even if there is more horizontal space for display and if all word properties are selected to be displayed, only word, pos and lemma are displayed:

The column widths are too low to display the values

Solution

1. extend to the right border the properties values table view on the right to show all/more properties
2. force activation of the horizontal scrollbar of the view (by default the scrollbar cannot be displayed and used)
3. Recompute the column widths when changing the displayed properties
