TableView column resizing policy & resizing issue

[brandonrock919]

1. Columns resizing policy missing - should be constrained/unconstrained (like the simple tableview) because of missing resizing policy columns will not fit for resizing apps
2. There is an issue with resizing - resizing columns can be pop out of the table

I've been trying to get over the same issue, and still haven't found a solution. Another thing i noticed was that when the table is too big for the scene, the table cuts the columns that don't fit in the far right, but when i scroll the content, the table stretches and the scroll bar disappear. I attached a small clip showing this happening
