In ark, when you open an archive, the archive's files are listed in rows - one row per file.
Each row has columns like 'Name, Size, Compressed, Mode and Date' in my case.

From these columns only the 'Name' column's width does not resize.

Reproducible: Always

Steps to Reproduce:
1.Open ark
2. Open an archive containing at least one file
3. Try to resize the 'name' column's width with the mouse

Actual Results:  
The 'name' column's width is not resizeable 

Expected Results:  
the 'name' column's width will resize as other columns.
