Noting that we've made some related updates mentioned here and here. Wanted to cross-post in case some folks here find that added functionality useful!
This thread is still tracking interest in the open feature request for user defined, persistent table column widths in the new table component. We've been noting down each +1 here on the related internal request for our eng team, so they're aware of the number of folks interested. Thanks for letting us know here that this would be useful to your Retool use cases 
We'll update here with anything new!
