I presume you can't just swap the second and third columns?

If the user can be satisfied with seeing one complete string at a time,
another option is to add a full-width label widget at the bottom of the
window showing the content of the second column of the currently
selected row. That avoids the need for the user to resize anything.

Or add tooltips to the column.
