title: How can I format a column of numbers in an emacs org mode table?
body: <p>I have a table in this form, in emacs <code>org-mode</code>. Please, is there a way to format the numbers in columns 3 and 4 to line the decimal points up vertically?</p>
  
  <p>Note, an aside: I sorted the resulting file using bash <code>sort</code> command, and found that the extra <code>|</code> at the start of each line is counted as column 1, so, for instance the column headed <code>OUTPUT</code> is number 4 in this context.</p>
