BootStrap带样式打印

在新窗口打印时bootstrap表格的样式出不来，因为打印时没有加载CSS样式。

我在jquery.PrintArea.js的基础上改造了下打印的方法：

(function ($) {
    var printAreaCount = 0;
    $.fn.printArea = function () {
        var ele = $(this);
        var idPrefix = "printArea_";
        removePrintArea(idPrefix + printAreaCount);
        printAreaCount++;
        var iframeId = idPrefix + printAreaCount;
        var iframeStyle = 'position:absolute;width:0px;height:0px;left:-500px;top:-500px;';
        iframe = document.createElement('IFRAME');
        $(iframe).attr({
            style: iframeStyle,
            id: iframeId
        });
        document.body.appendChild(iframe);
        var doc = iframe.contentWindow.document;
        $(document).find("link").filter(function () {
            return $(this).attr("rel").toLowerCase() == "stylesheet";
        }).each(
                function () {
                    doc.write('<link type="text/css" rel="stylesheet" href="'
                            + $(this).attr("href") + '" >');
                });
        doc.write('<div class="' + $(ele).attr("class") + '">' + $(ele).html()
                + '</div>');
        doc.close();
        var frameWindow = iframe.contentWindow;
        frameWindow.close();
        frameWindow.focus();
        frameWindow.print();
    }
    var removePrintArea = function (id) {
        $("iframe#" + id).remove();
    };

    $.fn.printAreas = function () {
        var ele = $(this);
        winname = window.open('', "_blank", '');
        var doc = winname.document;
        $(document).find("link").filter(function () {
            return $(this).attr("rel").toLowerCase() == "stylesheet";
        }).each(
                function () {
                    doc.write('<link type="text/css" rel="stylesheet" href="'
                            + $(this).attr("href") + '" >');
                });
        doc.write($(ele).html());
        doc.close();
        winname.print();
    }

})(jQuery);

前台调用的时候，把table放在一个div里，打印div即可：

       <div class="ibox-content" id="divprint">
                            <table id="tablePrint" class="footable table table-stripped toggle-arrow-tiny" data-page-size="8">
                                <thead>
                                    <tr>
                                        <th class="text-center">项目</th>
                                        <th class="text-center">部门</th>
                                        <th class="text-center">营业收入</th>
                                        <th class="text-center">利润</th>
                                    </tr>
                                </thead>
                                <tbody>
                                    @foreach (var item in Model)
                                    {
                                        <tr>
                                          <td class="text-center">@item.ProjectName</td>
                                          <td class="text-center">@item.DepartNameS</td>
                                          <td class="text-right"><a onclick="loadDetail('@item.ProjectId','@item.DepartId')">@item.InComeS</a></td>
                                   <td class="text-right"><a  onclick="loadProftsDetail('@item.ProjectId','@item.DepartId')">@item.ProfitS</a></td>
                                       </tr>
                                    }
                                </tbody>
                            </table>
                            <div class="dataTables_paginate paging_bootstrap pagination">

                            </div>
                        </div>

js调用：

   //打印
        $("#print").click(function ()
            $("#divprint").printAreas();
        });
