title: WEBI find duplicate rows (with exception of certain columns) and highlight
body: <p>consider the following table:</p>
  <pre><code>+------+------+----------+----------------+
  | Col1 | Col2 |   Col3   | Numeric Column |
  +------+------+----------+----------------+
  | ValA | ABC  | Value 3  |            101 |
  | ValF | DEF  | Value 10 |            101 |
  | ValC | DEF  | Value 10 |            101 |
  | ValB | GHI  | Value 12 |            103 |
  +------+------+----------+----------------+
  </code></pre>
  <p>I would like to find duplicate rows by comparing values across multiple columns, and highlight the values in the [Col1] column when duplicate rows are found (OR highlight the whole row, whatever is easier). So in the above table I would like to compare values of the [Col2], [Col3] and [Numeric Column] columns.</p>
  <p>And in this example, ValF and ValC in [Col1] would be highlighted. I am not sure how to go about this.</p>
