Treetable colspan - TypeError

Webix JS
1

Hi,

trying to implement colspan as shown in this example: http://docs.webix.com/samples/60_pro/01_datatable/06_api/12_group_columns.html

After adding colspan: 2 to my Column, I get a type-error:

Error in building grid TypeError: Cannot read property ‘header’ of undefined

Any suggestions?

Hello,

Please, share the code of your DataTable. Usually, such error occurs when the provided colspan value is bigger than the quantity of subsequent columns that can be included into span.
