我需要一个帮助，我有很多报告有10到30列和20000或更多行，mi驱动程序是mongodb并且结果查询非常快，但是当创建带有库PHPExcel的文档表时太慢或者大约十分钟或多一点时间，我的代码只有一个bucle：
$row++;
$contUser = 0;
foreach ($data as $index => $objUser) {
$backgroundColor = $colorOdd;
if ($contUser % 2 == 0) {
$backgroundColor = $colorPair;
}
$field = $objUser->getFields();
$column = 0;
//case 'N°':
$sheet->setCellValueByColumnAndRow($column, $row, $contUser + 1);
$sheet->getColumnDimensionByColumn($column)->setAutoSize(true);
$sheet->getStyleByColumnAndRow($column, $row)->applyFromArray($styleArray);
$sheet->getStyleByColumnAndRow($column, $row)->getFill()->applyFromArray(array('type' => \PHPExcel_Style_Fill::FILL_SOLID, 'startcolor' => array('rgb' => $backgroundColor)));

答案 0 :(得分：0)
首先，不要为您编写的每个单元格设置列样式（例如setAutoSizing为true）....编写所有数据，然后对该列应用自动调整大小。
与细胞样式相似......它们都是相同的，所以不要将它们应用于每个单独的细胞，但是在完成单个细胞的编写后应用于整个范围。 如果它是行的背景颜色，则应用于行范围，但不是每个单独的单元格。
