Answer 1

I'd try to reduce effort.

foreach ($this->CsInventory as $value) 
    { 
        foreach ($value as $key => $item)
        {
             $value[] = $item;
             $rdata .= "<td>$item</td>";

        }

       print_r($value)                  
    } 

As a general comment, not sure why you're adding anonomous values back to the $values stack, might be better to use a different array.
