Add option to disable column resize on specific column in STable

[kiaking]

It would be cool to have a option to disable column resize on table, not all but for specified column.

The use case is when we have big table with lots of column, adding empty last column makes the UI a bit nicer similar to what GitHub project has.

In this case, we wanna disable resizing the last empty column because there's no point of doing it, and it always allow table to have good background color (if we resize the last item, we get black bg color).

API idea.

const table = useTable({
  columns: {
    lastItem: {
      resizable: false
    }
  }
})
