如何在數據表中設置垂直數組？

HTML代碼

<table id="result_table" class="display table table-bordered" cellspacing="0" width="100%"> 
       <thead> 
        <tr> 
         <th>#</th> 
         <th>Username</th> 
         <th>Activation Status</th> 
         <th>Recent Login</th> 
         <th>Total No. of login</th> 
         <th>Avg No. of login/day</th> 
         <th>Total No. of Exports</th> 
         <th>Total No. of access</th> 
        </tr> 
       </thead> 
       <tfoot> 
        <tr> 
         <th>#</th> 
         <th>Username</th> 
         <th>Activation Status</th> 
         <th>Recent Login</th> 
         <th>Total No. of login</th> 
         <th>Avg No. of login/day</th> 
         <th>Total No. of Exports</th> 
         <th>Total No. of access</th> 
        </tr> 
       </tfoot> 
      </table>

，我必須加載AJAX調用表中的數據在JSON數據類型在這裏我的PHP代碼

while($row = mysql_fetch_array($run_query)){ 
    $name = $row['first_name']; 
    $name_string = "<a edit_id='name_".trim($name)."' href='#' onClick=\"click_today('{$name}');\" data-toggle='modal' data-target='#myModal'>{$name}</a>"; 

    //onClick=\"click_today('{$name}');\" 
    $result_array[] = array($row['id'], $name_string, $row['last_name'], $row['job_title'], $row['salary'],"-","-","-"); 
} 
echo json_encode($result_array);

acutually我的結果是（樣本輸出）
