phpword使用TemplateProcessor对模板进行替换

最近有个需求，对一个docx模板文件进行内容替换，这里记录一下遇到的一些难点和解决办法

1.单个表格替换，其中第一列需要纵向合并动态数量的单元格
模板名称:${table}
代码：

$tableStyle = array(
    'borderColor' => '000000', // 边框颜色（黑色）
    'borderSize' => 6, // 边框大小（6/8 磅）
    'cellMargin' => 50, // 单元格内边距
    'alignment' => \PhpOffice\PhpWord\SimpleType\JcTable::CENTER, // 表格居中
);
$resultTable = new \PhpOffice\PhpWord\Element\Table($tableStyle);
                $modelName = $model["name"];
                $row = $resultTable->addRow();
                //设置表头
                $row->addCell(2500,['bgColor' => '#B6DDE8'])->addText("content1", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                $row->addCell(3000,['bgColor' => '#B6DDE8'])->addText("content2", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                $row->addCell(2000,['bgColor' => '#B6DDE8'])->addText("content3", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                $row->addCell(2000,['bgColor' => '#B6DDE8'])->addText("content4", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                foreach ($model["children"] as  $key=>$child){
                    $resultTable->addRow();
//重点，需要合并的纵向单元格第一个的style设置["vMerge" => "restart"]，后面的单元格设置["vMerge" => "continue"]
                    if ($key == 0){
                        $resultTable->addCell(2500,["vMerge" => "restart"])->addText($modelName, array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                    }else{
                        $resultTable->addCell(null,["vMerge" => "continue"]);
                    }
                    $resultTable->addCell(2500)->addText("text1", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                    $resultTable->addCell(2000)->addText("text2", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                    $resultTable->addCell(2000)->addText("text3", array('name' => 'Arial', 'size' => 14, 'color' => '000000', 'bold' => true));
                }
                //最后将字符串替换为整个表格
                $tmpTemplateProcessor->setComplexBlock("table", $resultTable);

2.将一个字符串替换为复杂的多段文字，多个表格模块
逻辑：先将单个字符串的占位符替换成多个占位符，然后将docx保存为临时文件，重新读取，再将对应的段落和表格替换。注意这里有个坑，setComplexBlock会将段落所有的内容都替换掉，如果你只有一个段落但是里面有很多占位符，多次使用setComplexBlock后，只会有一个替换后的内容显示。
占位符：
${safe_table_block}
${safe_table}
${/safe_table_block}

$modelListStringArr =["parahraph_1","table_1","parahraph_2","table_2"]
//生成多个段落占位符
$templateProcessor->cloneBlock('safe_table_block', count($modelListStringArr), true, true);
        // 替换每个块中的占位符
        foreach ($modelListStringArr as $index => $paragraph) {
            $templateProcessor->setValue('safe_table#' . ($index + 1), htmlspecialchars($paragraph));
        }
