php - PHPWord 的 HTML 阅读器不能处理表格?

当我使用 Html 阅读器将我的 html 转换为 docx 时,阅读器被切断了我的表格。

PHP 示例:

$reader = IOFactory::createReader('HTML');
$phpWord = $reader->load($this->getReportDir() . '/' . $fileName);
$writer = IOFactory::createWriter($phpWord);
$writer->save($this->getReportDir() . '/' . $fileName);

表格示例:

<table>
<tr>
<td>№ п/п</td>
<td>Общие показатели результатов прохождения проверочных листов</td>
<td>Количество пройденных проверок</td>
<td>% от общего количества пройденных проверок</td>
</tr>
</table>

最佳答案

当前来自 PHPWord 的 HTML 类非常有限。您遇到的问题是已知问题(请参阅 https://github.com/PHPOffice/PHPWord/issues/324)。

我正在从事一个需要一些 HTML 表格来进行文档转换的项目。因此,我稍微改进了 HTML 类。它很少经过测试,我只是测试了 DOC 转换。

我的版本能够转换以下 HTML:

<table style="width: 50%; border: 6px #0000FF solid;">
<thead>
<tr style="background-color: #FF0000; text-align: center; color: #FFFFFF; font-weight: bold; ">
<th>a</th>
<th>b</th>
<th>c</th>
</tr>
</thead>
<tbody>
<tr><td>1</td><td colspan="2">2</td></tr>
<tr><td>4</td><td>5</td><td>6</td></tr>
</tbody>
</table>

生成以下 DOC 表:

有了这个新结构,很容易添加新的样式支持。您只需要编辑 parseStyle() 方法和 $stylesMapping 变量(在 getInheritedStyles() 方法中)。希望对您有所帮助。

使用示例:

<?php
include_once 'Sample_Header.php';

// New Word Document
echo date('H:i:s') , ' Create new PhpWord object' , EOL;
$phpWord = new \PhpOffice\PhpWord\PhpWord();

$section = $phpWord->addSection();
$html = '<table style="width: 50%; border: 6px #0000FF solid;">'.
'<thead>'.
'<tr style="background-color: #FF0000; text-align: center; color: #FFFFFF; font-weight: bold; ">'.
'<th>a</th>'.
'<th>b</th>'.
'<th>c</th>'.
'</tr>'.
'</thead>'.
'<tbody>'.
'<tr><td>1</td><td colspan="2">2</td></tr>'.
'<tr><td>4</td><td>5</td><td>6</td></tr>'.
'</tbody>'.
'</table>';


\PhpOffice\PhpWord\Shared\Html::addHtml($section, $html);

// Save file
echo write($phpWord, basename(__FILE__, '.php'), $writers);
if (!CLI) {
include_once 'Sample_Footer.php';
}
