I would like to display a table using TableView. My table already has headers, so I remove them using AppearanceElements -> {"CollapsedRowHeaders", "CollapsedColumnHeaders"}. When I do so though, the little triangle at the bottom right of TableView disappears and I can't resize it manually. I like to have this option so I can adjust the displayed table in TableView to the current size of the Notebook window.

As an example, compare:

data = Table[RandomReal[{1, 100}], 10, 20];
TableView[data,  ImageSize -> 700]

and

data = Table[RandomReal[{1, 100}], 10, 20];
TableView[data, AppearanceElements -> {"CollapsedRowHeaders","CollapsedColumnHeaders"}, ImageSize -> 700]

The question is: Am I naïve in thinking this should be an option all the time, or is something going wrong with the manual resizing tool when collapsing headers?

    $\begingroup$ You'll need to add "ResizeArea" to the AppearanceElements (when you overwrite the default option value, you effectively removed that part) $\endgroup$

    $\begingroup$ That being said, you could also just set your headers via the Headers option, then there might not even be a need to collapse them $\endgroup$
