Hello, @bjrmatos
In your example i'm seen the same problem, check screenshot.
column A have width 144px, but 1200 * 4.55% = 54.6. The same problem with column B. From what i have researched, column A have same width as column F, column B like G, but now column C don't looks like H, it's coz width of C defined greater than H.
Overflow for some reason don't work, attaching screenshot too

Attaching screenshot with real data, u can see last row a little bit "cut", like row didn't expand completely.
