I think your trouble with the table has far more to do with the design (specifically color) choices made by the author.
1. You mentioned this in passing, but I'll repeat for emphasis: The contrast between a hovered/highlighted table row and ones that are not is too low. I have decent eyes and I also have a hard time seeing it.
2. Table rows (and/or columns) should be striped between two or more high contrast colors for better legibility. White, black, white, black for example. This table is all black through and through.
3. The table borders' contrast is way too low, it's hardly even visible. This combined with the singular row/column color makes legibility even worse.
TL;DR: Table itself is actually fine, the colors are terrible.
