I’m trying to apply a splitAt(4) on a grid but I got this error:

this.objBuf is undefined
[Break on this error] width+=parseInt(this[b_ar[1]][i]);thi…hType==‘px’)var n=“cellWidthPX”;else

dhtmlx…splt.js (line 8)

There is #rspan and #cspan in the header, but not on the selected column 4.

Please check if you don’t merge cell from right and left part of the grid. If issue still occurs please open ticket at support.dhtmlx.com/ and provide any kind of sample where issue can be reconstructed
