好的，我到目前为止所做的代码，但这只是从数据库中获取数据并循环它，我想为最后 2 个 cols 做一些安排。

我得到了 posicao、desc、quantidade、unitario 的数据，但是对于 iliquido 和 total，我想做一些计算。

对于 iliquido，我想制作 unitario*quantidade 并在列上显示所有结果。

对于总数，我想用 iliquido 值的总数（例如=sum（2ndrow：lastrow））制作一行。

您可以只插入作为 PHPExcel 单元格的值的公式，这些公式将作为常见的 Excel 公式。所以只要放：

=A$row*C$row

在您希望获得该行的 unitario*quantidade 结果的列中。总和也一样。

例如，当您执行此循环时：

while ($row = mysql_fetch_row($result)) { 
   $col = 'A'; 
   foreach($row as $cell) { 
      $objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$cell); 
      $col++; 
   } 
   //add this line to get the unitario*quantidade result
   //in the last column
   //here I'm assuming that quantitade and unitario are placed
   //in column A and C in your excel, but this may be wrong, so
   //replace them with the proper values
   $objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,"=A$row*C$row");
   $rowNumber++; 
}
