mpdf中如何设置table的高度

How to set the height of table in mpdf

我正在使用 MPDF 生成发票。我的项目行是动态的,因此显示项目的 table 的高度应该是灵活的。当我使用以下代码打印 PDF 时:

    <!-- Latest compiled and minified CSS -->   
<?php echo $this->Html->css(array('bootstrap.min','AdminLTE.min','skin-green','font-awesome.min')); ?>
<style type="text/css">
  .products{
    width: 100%;
    border-collapse: collapse;
  }
  h2,h3{
    margin: 0;
    padding:0;
  }
  .border{
    border: 1px solid black;
    padding:5px;
  }
  table.products{
    border: 1px solid black;
    height: 500px;
    margin-left: -6px;
    margin-right: -6px;
    margin-bottom: -6px;
  }
  .products tr td{
    padding:5px;
    border:1px solid #333;
  }
  .products tr th{
    padding:5px;
    border:1px solid #333;
  }
  .pull-right{
    float: right;
  }
</style>
<!-- title row -->
<div class="border">
  <table width="100%">
    <tr>
      <td style="width:35%">

      </td>
      <td style="width:35%" align="center">
        Estimate
      </td>
      <td style="width:35%" align="right">
        Date: <?php echo  date('d-m-Y',strtotime($invoice['Invoice']['dated'])); ?>
      </td>
    </tr>
    <tr>
      <td colspan="3" align="center">
        <br>
        <h3>Invoice Heading</h3>

      </td>                
    </tr>
  </table>
  <hr/>
  <div class="row">
    <div class="col-xs-12 border-right">

            <th width="60"><?php echo __('Sr. No.'); ?></th>
            <th><?php echo __('Quantity'); ?></th>
            <th width="250"><?php echo __('Particulars'); ?></th>
            <th><?php echo __('Rate'); ?></th>
            <th><?php echo __('Amount'); ?></th>
          </tr>
        </thead>
        <tbody>
          <?php $i = 0; foreach ($invoice['InvoiceDetail'] as $invoiceDetail): $i++; ?>
            <tr>
              <td><?php echo $i; ?></td>
              <td><?php echo $invoiceDetail['quantity']; ?></td>
              <td><?php echo $invoiceDetail['Item']['name']; ?></td>
              <td><?php echo $invoiceDetail['price']; ?></td>
              <td align="right"><?php echo $invoiceDetail['amount'] ?></td>
            </tr>
          <?php endforeach; ?>
            <tr> 
              <td colspan="3"></td>             
              <td>Total: </td>
              <td align="right"><i class="fa fa-inr"></i> <?php echo number_format((float)$invoice['Invoice']['total'], 2, '.', ''); ?>
              </td>
            </tr>  
            <tr>
              <td colspan="5">Amount in words: Rs.<?php echo $c2w ?></td>
            </tr>
        </tbody>                  
      </table>
    </div><!-- /.col -->
  </div><!-- /.row -->
</div>          

打印pdf如下:

但是我需要打印如下:

我试过使用 line-height 但它会扭曲视图,因为 td 中的 valign 不会将内容对齐到顶部。

在 TD 打印中使用 line-height:100px 如下所示:

有没有办法通过动态增加项目 table 的高度来填充整个页面。

我在搜索 mpdf 行高时发现了这个未回答的问题。

这是我用过的一些解决方案。

选项 1

  1. 计算循环中的每一行
  2. 估计每一行的大致高度。通常这是固定在一行中的,所以这不是问题。
  3. 从table
  4. 的要求高度中减去(行数x高度)
  5. 在循环中,如果行号等于总行数,则它是最后一行,在这种情况下,您可以为最后一行添加 <td height="##">

选项 2

添加填充行

  1. 算出发票上需要多少行才能填写正确的金额(保持小于最大值)
  2. 然后使用类似下面的东西填充 table 之后

    if($current_row < $total_rows){ for($i=$current_row; $i<$total_rows; $i++){ echo '<tr><td colspan="4"></td></tr>'; } } ?>

您必须在单元格内指定它,如下所示:

<td  style="height:4.6cm; vertical-align: text-top;"></td>

这是我用过的一些解决方案。

  1. 统计 tbody
  2. 中的所有 tr
  3. 然后使用 css set line-height of td
  4. 找到 tbody 的最后 tr

根据mPDF库的文档here,我们只能设置块级元素的高度。我遇到了同样的问题,然后我将我的 table 移到 div 中,并将高度添加到 div 中,如下所示。

<div height="870" style="border:solid 1px #ccc">
    <table class="table>
         Your table content here...
    </table>
</div>

@jecorrales 问我如何解决我的问题。

我使用简单的 window.print() 打印了发票,但使用 css 设置如下:

    <style type="text/css">
  @page {
      size: 21cm 29.7cm;
      margin: 0; /* change the margins as you want them to be. */
  }

  body  
  {
      /* this affects the margin on the content before sending to printer */ 
      margin: 0px;  
  } 
  .row1{
    margin-right: -12px;
    margin-left: 0px;
  }

    width: 100%;

  }

  }

其中 $invoice 包含数据数组。

我正在定义静态编号。单个 A4 页面可以支持的行数。并针对这种情况使用此解决方案超过 2 年。
