你可以试试这个功能。将您的表放在具有唯一 ID 的 div 中，然后在 JQuery 中引用它:

<script>function printDiv() {
                    var divName= "<DIV ID HERE>";

                     var printContents = document.getElementById(divName).innerHTML;
                     var originalContents = document.body.innerHTML;

                     document.body.innerHTML = printContents;

                     window.print();

                     document.body.innerHTML = originalContents;
                }</script>
