@namjul hey thank you so much, worked like a charm.

@namjul it works perfectly. Thanks a lot.

In my case it doesn't works perfectly. The alignmet is correct but every pipe add a space at the start of the row.
For example, the first row is:

| pippo | pluto | paperino |

then I start the second row and hapens this:

␣ | pippo | pluto | paperino |
␣ |*

and when I start second column in the second row another space will be added:

␣ ␣ | pippo | pluto | paperino |
␣ ␣ | one   |* 

(I used " ␣ " to represent a single space and "*" to represent cursor position at the time)

Anyone could figure why?
