Looks good so far please see comments

• Also when in edit mode, I think we might need a horizontal scrollbar but I would prefer if we could get it to fit without one. It is also possible to edit the column where the delete button is meant to be in for the substrate roughness while I don't think it would lead to any issues would be nice to disable edit in that column.
• I cannot edit the mu and sigma values
• It would be nice to have the fit header toggle the checkboxes similar to https://gist.github.com/StephenNneji/14bfc4e7a322ec89df7d30847fbf19b3?permalink_comment_id=2588841#gistcomment-2588841 but we could do later if useful

@StephenNneji your comment on not being able to edit the mu and sigma values: they're set to only be editable if prior_type is set to gaussian (which I think we agreed on in a meeting). otherwise they should be greyed out, or at least they are on my machine? they don't look to be on yours

I can confirm that it works, I was testing on Ubuntu and it does not grey out the cells. Also the dropdown feels finicky, it doesn't enable the mu and sigma except I press enter or click another cell. The inf spinbox does nothing when the value is infinity and I press the down button, I am not sure the appropriate behaviour for an inf spinbox but I think if possible the button should be disabled if it does nothing or jump to a reasonable start value maybe?

Almost there, A few cosmetic things

• I think the widgets on top need some layout tweaks especially in edit mode so the widget is closer to the labels
• Can we make the header title case ?

Good Job, Thanks for the hard work on this one.

I am getting a lots of user warning when I change the fit, please have a look if it something we need to fix or just silence

@StephenNneji this seems to be a python-RAT bug in the new version when you use Project.model_dump(): see the following code produces the same warning

from RATapi import Project
p = Project()
p.model_dump()

so i've created the issue RascalSoftware/python-RAT#90 for it
