someone has tried to see what happens sorting on a column that contains null values ?
Actually, I just reintroduced support for sorting on null values this morning. I had inadvertently removed it when I moved the class out of TableView.
And with this change, will it be possible to have the sort also on multiple columns (useful in some cases) ?
Yes, you can currently sort on multiple columns. Left-click to sort on any single column. Shift-left-click to add another column to the sort. You can see an example in the Kitchen Sink demo.
what do you think on adding an optional style to change the background color on all the column/s being sorted (only a little, using a similar color to that currently used) ?
This is already supported via the "columnSelectionColor" style.
