Is there a way to modify the total width of the left side columns

Gantt React Gantt

I would like to add several columns but I can’t seem to inrease the width of the left side of the gantt so that it will show all the columns.

Is there a css variable that I can override for this?

Hi,

You can init gantt like

<Gantt grid={{width: 400}}
