This is a variation of James Donnelly's answer to a clickable link in a TD question. I found a case where his answer doesn't completely work.
Here is the example in JSFiddle
I added vertical-align to td and lots of text to Parent1.
table.coolTable td {
vertical-align:top;
...
The problem is that the empty space under Parent2 is not clickable. How do I get that part clickable too? Specifying fixed unit heights works but I don't want to constrain my table with fixed heights.
Thanks!
