somehow this problem is still present

More precisely, it works for the first column(s) (the label columns), but not the data columns. If the header length is longer than the width for data cell, it is not shown entirely. For testing, we can use:

arr = zeros('a=a_long_label,another_long_label')

Still not fixed :) For the "index" columns, it only take axes names into consideration, not labels.

arr = ndrange('a=long_long_long;b=b0,b1')

Also the axes "view" width is not reset when going from one array to another, which means it desync with the "vlabels" view, leading to odd results.
