使用 TCPDF 创建 pdf 时，表头和正文在第二页中未对齐

Question

我想用 TCPDF 生成一张发票，其中包含一个取决于项目大小的动态表。它工作正常，直到表格大小不超过第一页。从第二页开始，表头向左移动，这打破了表头和表体之间的对齐。我不知道如何解决这个问题！ 注意：我没有多张桌子。这是单表发票。

<table style="font-family:Arial, Helvetica, sans-serif;border: 1px solid #ddd;padding: 3px">

Answer 1

我也有同样的问题，结果是因为我在 writeHTML 之前使用 SetX 设置了 X 位置

$pdf->SetX(6);
$pdf->writeHTML($tbl_string, true, false, true, false, 'C');

我刚刚删除了SetX，现在就可以了

$pdf->writeHTML($tbl_string, true, false, true, false, 'C');
