    int_col("I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I2I23", [4, 5, 6]),

Shouldn't it be based on available space?

We want this constant to be defined in the theme so it can be changed manually if needed. Take a look at the calculateColumnWidth method - we already have a minColumnWidth, we could just define a maxColumnWidth that it uses and never go over that.
Note this doesn't address #1284, but that's fine and can be addressed in a separate PR.

I can take on #1284 after this one. I think it'll be somewhat related anyways
