title: Select table cells in a column based on the column header text
body: <p>How can I select the cells in a column based on what text is written in the table column header, e.g., "Status", using <code>Javascript</code> or <code>jQuery</code>?</p>
  
  <p>(Details, not part of the question: I want to later use this to apply background-color to the cells in that column based on the cell content, so that for example 'Error' would get the background-color red and 'Quality OK' would be white.)</p>
