Question

我是TCPDF PHP库的新手，用于创建pdf。我可以打印表格的第一列但无法打印其余表格。这是我的代码

<html>
<head>
<title>Admit Card</title>
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet">
<script src="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/js/bootstrap.min.js"></script>

<style>
@media print {
  @page { margin: 0; }
  body { margin: 1.6cm; }
}
</style>
<script type="text/javascript" src="library/jquery-1.8.3.js" > </script> 
<script type="text/javascript">

    function PrintElem(elem)
    {
        Popup($(elem).html());
    }

    function Popup(data) 
    {
        var mywindow = window.open('', 'admit', 'width=800');
        mywindow.document.write('<html><head><title></title>');
        /*optional stylesheet*/ //mywindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
        mywindow.document.write('</head><body >');
        mywindow.document.write(data);
        mywindow.document.write('</body></html>');

        mywindow.print();
        mywindow.close();

        return true;
    }

TCPDF输出文件中的结果是只有mysql上面的第一个内容才能连接。第一列变量是打印。结果如下

TCPDF Example Dummy Dummy

Sl. No.   Name & Father Name  Nos.    Roll Number   Photo     Signature       Remarks




001





002





003





004

Answer 1

我想到的问题是由于正确的表格列高度和宽度。在为所有柱子设置适当的高度和宽度之后，即在td字段中，剩余场能够获得值。如果没有正确的表属性，则Tcpdf不会打印值。问题现在解决了。

TCPDF有些变量不在输出文件中打印？
