Set column widths on Composable table using HeaderCellSelect

[TRegan3]

I'm using a Composable table in a create-react-app. I have a HeaderCellSelect in the HeaderRow and a CellSelect in the Body Row.

Are there any examples of how to set the column width of the HeaderCellSelect/CellSelect column?

I have a 4-column table, with this as the first column, and it takes up 1/4 of the table width no matter what I try. I'm using Tailwind css, so a Tailwind example would be fantastic, but any example of how column widths can be set on a Composable table would be wonderful.
