hi,

just like @Alban B. said, you can use column's width option, example:

{ label: 'Position', field: 'position', sort: false, width: 350 },

I think I can try and give you a generic answer (not having an actual code snippet) before the mods might give you a more structured one.

This is a basic column obj with a fixed position on the left, cell background and fixed width.

columns: [
  {
    label: "Item",
    field: "col1",
    accessor: "col1",
    fixed: "left",
    bgColor: "black",
    width: "200px",
  },
