Rowspan on several lines in header

Hello,

I am using version dhtmlxTreeGrid_v14_Pro_70813 of the grid.

I need to build a header with cells having a rowspan on more than two lines.

It seems that version 1.5 has method setRowSpan() that handles that.

My questions are :
1.    Is it possible to have a cell rowspan on several lines in header with my current version (dhtmlxTreeGrid_v14_Pro_70813) ? (by XML or by scripting)
2.    Do I need to upgrade to version 1.5 or is it possible to do that by adding some code to my current version?

Many thanks in advance,

Best regards,

This method need to be used if you need to create a rowspan inside data part of grid, it not related to header structure

>>1.    Is it possible to have a cell rowspan on several lines in header with my current version
Yes, your version already has all necessary functionality, you can do it as

mygrid.setHeader("A0,B0,C0")
mygrid.attachHeader("#rspan,B1,C1")
mygrid.attachHeader("#rspan,B2,C2")

in result, first column will have a rowspan for all header lines; you can create any complex col|row spans by using #rspan and #cspan as grid headers values.

Thanks for the fast answer, your solution works fine.
