Thank you very much, fiddlosopher. I'll try with a lua filter which sets 
all column width to an equal size:
```lua
function myfunction(el)
    -- divide 1 by number of columns
    -- subtract some spacing
    equalwidth = (1 / #el.colspecs) - 0.01
    -- print(equalwidth)
    -- walk through colspecs
    for idx, _ in ipairs(el.colspecs) do
        -- set width per column
        table.insert(el.colspecs[idx], equalwidth)
    end
    -- return Table element
    return el
end

return {{ Table = myfunction }}
```
