Some example about Gantt chart with igrid?

Gantt chart implies cells merged horizontally and arrows over the grid, but iGrid ActiveX does not allow to do this. Sorry, but the original ideology of iGrid is to be an enhanced and editable replacement for such controls as ListView and FlexGrid, so you need to search for a more specialized control.

We can do things that looks like Gantt for one week only
5 days 7 hours per day (France) = 35 cells
the same background color without the grid etc.
