fyi: I am using a custom IComparer<keyvaluepair<string, string="">> for sorting, but, that's working as expected.

The problem coexists with DataTable is that I cannot change text font of cells. And because of the language I'm using (Persian), I need to perform RightToLeft function. It's so easy in DataGridView's native properties but I don't know hpw to change font, alignment, and RightToLeft properties in DataTable.
