title: How is table cell height calculated?
body: <p>After a couple of days spent struggling with HTML tables, my forehead has a grid of indents which incidentally are a mirror copy of my keyboard.</p>
  
  <p>Speaking of grids, I'd like to know if there's any <em>set of rules</em> regarding <code>&lt;td&gt;</code> size.</p>
  
  <p>Is it all according to the content? Is it affected by other cells in the same row? By the row itself? By the table? Plain ol' CSS?</p>
  
  <p>NOTE: I'm specifically not looking for an answer to a specific question.<br>
  I just want to know how the darned height is <em>calculated</em> so I can figure out myself each time what to expect.</p>
