Resizing of table or changing size of the cells in Writer does not work. [I'll create a different bug for changing the cursor handle there too.]
(In reply to Jan Holesovsky from comment #0) > [I'll create a different bug for changing the cursor handle there too.] The pointer does change when the mouse moves over a row or column edge. Now coming to the main problem, while digging through the code to find the correct LOK API to accomplish this, it seems to me that such an LOK API is not exposed yet. I tried re-sizing the row/column size using setTextSelection and setGraphicSelection LOK APIs but as I suspected they don't do what we really want to do here.
Resizing table cells now works nicely thanks to Tomaž Vajngerl's work. Resizing the whole table is still not supported in a convenient way.
