Looking more closely at the csv file, it is missing the last line, which should be "1,0.4,0.01,17". If you add that line to the csv file, table to structured grid runs just fine. (At least it runs fine on ParaView 4.4.0. I don't have a version that old handy to try it on.) See the attached screenshot.

I have no problem converting it to points using the “table to points” filter, However, Paraview crashes as soon as I try to run the “table to structured grid” filter. Just before Paraview crashes, it gives the following error message:
