Of course not. You just need an algorithm that put the data into the Data 
property of the TableView each time it requests it, by raising the Data event 
and by giving you a row and a column number.

The difference between GridView and TableView is that GridView creates a 
internal object for each cell in the grid, even if it is void, whereas the 
TableView creates nothing, so can display tables of any size.

I admit there are some problems in the TableView, with refresh, cursor 
updates, ... mainly because of strange things happening with this QT widget. 
If I remember, this is the reason why I didn't highlight the current cell, 
for example. But things may have change, since the time I implemented this 
widget.
