I don't believe there is a way to adjust the column width. Qlik Sense uses responsive design to optimize the visuals for any screen size so setting the columns width would be counter productive. That said, the display you are getting is not what we want. I have play around with my data and I am not getting the same results. Would you be able to post the QVF?
Ok, I could reproduce this by just loading inline 2 rows of data. The qvf is attached.
Another thing, I'm used to the Qlikview editor and miss the built in load inline interface in Qlik Sense...
