Timeline columns are too wide

I tried several options to have smaller column widths but the system keeps applying a css value of 70px which is too wide for my chart. I am quite happy to write code if needed but was hoping there was a better way of doing it. There is a min width setting but no max width setting and I need one of those basically.

Hello,
Usually, Gantt changes the width depending on the number of visible cells:

If you set the minimal column width to 1 and resize Gantt container or move the task to a different position, the column width will change:

I did get the min_width attribute to work, but to me that was not a good name because that’s the widest or max width. But for now it seems to work. Thanks!!
