Small correction. First attempt was with a table which did not have a width 
at all.
Here is the version which will add or replace the width.

```lua
function myfunction(el)
    equalwidth = (1 / #el.colspecs) - 0.01
    for idx, csp in ipairs(el.colspecs) do
        csp[2] = equalwidth
    end
    return el
end

return {{ Table = myfunction }}
```
