这种方法可以在打印的页面中添加样式，新页面跳转打印
doPrint(ids){ var titleHTML=document.getElementById(ids).innerHTML; var OpenWindow = window.open(""); OpenWindow.document.write('<!DOCTYPE html><html lang="zh-cn">'); OpenWindow.document.write("<head>"); OpenWindow.document.write('<meta charset="utf-8">'); OpenWindow.document.write('<title></title>'); OpenWindow.document.write('<style>.table{width: 100%;font-size:13px;}</style>'); OpenWindow.document.write('</head>'); OpenWindow.document.write('<body><div class="layout-g-content" id="p">'); OpenWindow.document.write('</div></body>'); OpenWindow.document.write('</html>'); OpenWindow.document.getElementById("p").innerHTML= titleHTML; window.setTimeout(function(){ OpenWindow.print(); OpenWindow.close(); }, 500); },
