jva This is because allowing both row selection and column selection is exactly the same as enabling cell selection. No tool tips were suppled for the name columns since they seemed self-explanatory.

The following code implements the tool tips. In its default configuration, a table supports a selection that consists of one or more rows.

Now press the mouse button and drag to the right or left. In a subsequent example, newFilter is invoked every time the text field changes.

Instead, a single cell renderer is generally used to draw all of the cells that contain the same type of data.
