Some questions about the grid.

Hi
sorry for my bad english.
I'm trying to use your object to view some data (from an xml file) with your grid, but I'm a newbie and i need help.

1) Could i know how to have a simple grid with movable colums?
I mean that clicking on the column header and holiding it the user can move it.

2) I have 2 tables (master/detail) how clould i display in only one grid?

3) Is it possibile to have vertical text headlines?
