a big problem is, if i scroll this table with vertical scrollbar, then it will select the wrong cell by mouse clicking on

I run into the following issue

1. Double click any cell to edit
2. Click on any other row
3. The cell that was previously selected will disappear

This can be resolved by adding the following line to the end of cancelEdit:
setContentDisplay(ContentDisplay.TEXT_ONLY);
