GridView component

[Gulvan0]

It is quite logical to expect TableView to treat its contents as individual cells rather than rows. It may not be a default behaviour (that needs to be discussed separately), but at least the mode parameter with "row", "column", "cell" as possible values would be a nice addition. That way, the following should ideally become possible:

• Cell-wise/column-wise selection and hover effects
• Cell-wise/column-wise styling (maybe support custom item-renderers for such modes as well)
• Cell-wise/column-wise events (MouseEvent.CLICK is the most important one)

Optionally, it may be also convenient to simplify the logic corresponding to the datasource, i. e., allow the user to append columns to the column-based TableView in the exact same fashion as rows to the row-based TableView. For cell-based TableView, some another approach may be used (two-dimensional datasource maybe?).

Finally, at the moment, one may create a column header using the <header> tag, but there's no way to do the same for rows. This is also a feature that seems to be important and useful.
