Hover for a different set of table elements

i have 4 rows, 3 columns. two columns are set to orange, while in the last columns i set a background-color to green. i set background-color hover for a rows to red. also i set same background-color hover to last columns, just trying to make it highlighted when i points a mouse over it anywhere on each rows and columns. i want red color highlights all the rows and columns when a mouse points to any row/column.

   <tr>
   <td>OrangeA1</td>

   </tr>

   <td>GreenC3</td>
   </tr>
