我有一张大桌子，我想打印或转换为pdf 。
现在问题是大部分列都留给了打印。
我不知道打印为columns为left的原因。
请参考（以下代码段不起作用）Jsfiddle ：https://jsfiddle.net/85okepx8/12/
以下是演示：
$('#print').click(function(){
$('#examples').printThis();
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/printThis/1.12.2/printThis.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<a href="#" class="btn btn-warning" id="print">Print</a>
<table class="table table-boardered" id="examples">
<thead class="thead-dark">
<tr>
<th>Id</th>
<th>Customer Name</th>
<th>Description</th>
<th>Order Number</th>
