我想将样式信息从单元格复制到范围,例如Excel中的Format Painter。该文档说要执行以下操作:
$activeSheet->duplicateStyle($activeSheet->getStyle('A1'), 'D1:D100');
$activeSheet->duplicateStyle($activeSheet->getStyle('B1'), 'E1:E100');
似乎有一个错误,因为D1:D100和E1:E100都从单元格B1获得样式。如果更改两行的顺序,则两个范围都将从A1获得样式。同样,
$styleA = $activeSheet->getStyle('A1');
$styleB = $activeSheet->getStyle('B1');
$activeSheet->duplicateStyle($styleA, 'D1:D100');
导致D1:D100从单元格B1获取样式信息。最后的getStyle值用于所有重复的样式结果中。
我确信PHPExcel的将来版本将有修复程序,在此之前,我只需要找出解决方法。
一种解决方法是使用xf索引样式:
$xfIndex = $activeSheet->getCell('A1')->getXfIndex();
然后为该范围内所有单元格的xfIndex设置该值
for ($col = 'D'; $col != 'E'; ++$col) {
for ($row = 1; $row <= 100; ++$row) {
$activeSheet->getCell($col . $row)->setXfIndex($xfIndex);
}
}

或者,将修复程序应用于Classes / PHPExcel / Worksheet.php中的plicateStyle()方法
第1479至1486行当前显示为:
if ($this->_parent->cellXfExists($pCellStyle)) {
// there is already this cell Xf in our collection
$xfIndex = $pCellStyle->getIndex();
} else {
// we don't have such a cell Xf, need to add
$workbook->addCellXf($pCellStyle);
$xfIndex = $pCellStyle->getIndex();
}
改成:
if ($existingStyle = $this->_parent->getCellXfByHashCode($pCellStyle->getHashCode())) {
// there is already such cell Xf in our collection
$xfIndex = $existingStyle->getIndex();
} else {
// we don't have such a cell Xf, need to add
$workbook->addCellXf($pCellStyle);
$xfIndex = $pCellStyle->getIndex();
}
类似地,在Classes / PHPExcel / Style.php中的applyFromArray()方法中
第425至432行当前显示为:
if ($workbook->cellXfExists($newStyle)) {
// there is already such cell Xf in our collection
$newXfIndexes[$oldXfIndex] = $existingStyle->getIndex();
} else {
// we don't have such a cell Xf, need to add
$workbook->addCellXf($newStyle);
$newXfIndexes[$oldXfIndex] = $newStyle->getIndex();
}
改成:
if ($existingStyle = $workbook->getCellXfByHashCode($newStyle->getHashCode())) {
// there is already such cell Xf in our collection
$newXfIndexes[$oldXfIndex] = $existingStyle->getIndex();
} else {
// we don't have such a cell Xf, need to add
$workbook->addCellXf($newStyle);
$newXfIndexes[$oldXfIndex] = $newStyle->getIndex();
}

现在,已将Fix推送到github上的developer分支。根据使用的样式的数量,它确实会给性能带来轻微的影响。明天晚上我将尝试获得更快的版本
