当我使用
Html阅读器将我的html转换为docx时,读者被切断了我的桌子.
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>
解决方法
PHPWord的当前HTML类非常有限.您遇到的问题是一个已知问题(参见
https://github.com/PHPOffice/PHPWord/issues/324).
我正在一个需要一些HTML表来进行文档转换的项目.所以,我的工作有点改进HTML类.它很少测试,我只是测试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： 它使用PHPWord版本0.13： <?php

有了这个新结构,很容易添加新的样式支持.您只需要在getInheritedStyles()方法中编辑parseStyle()方法和$stylesMapping变量.希望能帮助到你. 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 PhpOfficePhpWordPhpWord();
$section = $phpWord->addSection();
$html = '<table style="width: 50%; border: 6px #0000FF solid;">'.
'<thead>'.
'<tr style="background-color: #FF0000; text-align: center; color: #FFFFFF; font-weight: bold; ">'.
'<th>a</th>'.
'<th>b</th>'.
'<th>c</th>'.
'</tr>'.
'</thead>'.
'<tbody>'.
'<tr><td>1</td><td colspan="2">2</td></tr>'.
'<tr><td>4</td><td>5</td><td>6</td></tr>'.
'</tbody>'.
'</table>';
PhpOfficePhpWordSharedHtml::addHtml($section,$html);
// Save file
echo write($phpWord,basename(__FILE__,'.php'),$writers);
if (!CLI) {
include_once 'Sample_Footer.php';
}
