Awesome, I love dataviz done with divs only :) No need for SVG. Also, good idea to use zebra colors.
I think we should make it clearer that the grid rows are row groups, as it's not immediately obvious.
Also, note that many parquet files have only one row group. In this case, the row is a horizontal stack bar of the column sizes. Still useful.

Really makes you think about row group size and its effects.
