unable to see the data simultaneously in data tables

Hi All

I was trying various options available with webix in order to see the two datatables to get populated, but I am not seeing any changes. Although some times I see data coming up I see data is flickering.

please find my code at

Please help me with proper API’s

Thanks

datatables can not share same column.
change columns: config.customColumns as columns: webix.copy(config.customColumns)
