If you want alternate colors for each table row, then a simple CSS should do it. This way, if you want to insert new rows dynamically, it will adjust the colors automatically.

.stripped-rows:nth-child(odd){
   background-color:red;
 }
.stripped-rows:nth-child(even){
   background-color:blue;
 }

and html ...

 <table>
 <tr class = 'stripped-rows'>
     <td>sad</td>
 </tr>
 <tr class = 'stripped-rows'>
  <td>sad</td>
</tr>
 <tr class = 'stripped-rows'>
   <td>sad</td>
</tr>

Maybe I'm misunderstanding, but it looks like you want to apply oddrowcolor or evenrowcolor to alternating rows - but in your actual php/html, I don't see those class names anywhere. They're not being put on the rows, so their rules wont be applied. Just add them to the appropriate <tr> tags in your php and it should work. Alternatively you could use the nth-of-type selector to apply the rules without altering your php: 

tr:nth-of-type(odd) {
    background-color: black;
}
tr:nth-of-type(even) {
    background-color: red;
}
