export a org table to ascii format (tabs) are not conserved, culprit orgtbl-to-tsv?

[Uwe Brauer]

Hi

I wanted to export a 4x4 table to ascii to insert it into a web fill in
interface. However the column get distorted. I tried to tabify or
untabify the buffer but it did not help.


The problem also occurs when I export the table using the 
orgtbl-to-tsv
