body: <p>i have three columns, where i need to combine all these three column values into single column. </p>
  
  <pre><code>Metric  count  value1      value2
  parlegi   2        -1         3
  mangol    13       4          0
  pizza     2       +12         -5
  jax       0        -2          2
  </code></pre>
  
  <p>Now i need to merge cells in each row,i mean to display table with two columns as shown below. so end user report should display like below</p>
  
  <pre><code>Metric        count/value1/value2 
  parlegi                 2/ -1/  3
  mangol              13/ 4/0
  pizza                 2/+12/-5
  jax                     0/ -2/ 2
  </code></pre>
  
  <p>and here for positive values color should be green and negative values it should be red and zero with blue color.</p>
