How to change the width of first column in plotly.js table

I creating a table using plotly javascript, but haven’t found a way to increase the width of the first column. I’ve attempted css styles using this below to no avail:

Does anyone have a suggestion for how to change the width of specific columns in a plotly javascript table?

Thanks

This is probably what you need: https://plot.ly/javascript/reference/#table-columnwidth

Excellent thanks, that worked. Completely missed that in the documentation.
