我正在使用table2excel.js将HTML导出到Excel，它工作正常。我想根据条件更改行或列的颜色。可以吗？

<table id="ExcelTable" style="text-align: left;display:none">
    <tr class="rpthide">
        <td class="Supplier" style="font-size:14px;"></td>
        <td class="ContractNo" style="font-size:14px;"></td>
        <td class="OrderNo" style="font-size:14px;"></td>
        <td class="Article" style="font-size:14px;"></td>
        <td class="Ordered" style="font-size:14px;"></td>
        <td class="ContainerNo" style="font-size:14px;"></td>
        <td class="ETA" style="font-size:14px;"></td>
        <td class="Dispatched" style="font-size:14px;"></td>
        <td class="AtPort" style="font-size:14px;"></td>
        <td class="Arrived" style="font-size:14px;"></td>

    </tr>
</table>

$("#ExcelTable").table2excel({
              // exclude CSS class
              exclude: ".noExl",
              name: "Yarn Status List",
              filename: "Yarn Status List" //do not include extension
          });

在td中使用span标记。例如：<td> <span style="color:red">6000</span> </td>
对我来说很好。

make preserveFont：为true则使用字体大小和字体粗细

$(function () {
        $("#exportexcel").click(function () {
            var $table = $('.table2excel');
            $table.removeData(); //data is removed, previous when data existed was preventing initialization of table2excel

            $table.table2excel({
                exclude: ".noExl",
                sheetName: "Demo_Report",
                filename: "demo_Report",
                fileext: ".xls",
                preserveFont:true,
            });
        });
    });

是的，你可以改变颜色，你应该使用PreserveColor：真选项，这已经在table2excel github repo和字体大小和字体权重我已经在下面的主文件中进行了更改，我分享你我的table2excel原始代码和PreserveFont选项是由我做的，所以你可以使用它。它让你的字体大小和字体权重从你的表

我建议你使用更好的工具，比如ExcellentExport.js，你可以将任何css样式应用到html表格中，并且它们将在输出中导出。
样本使用：

<script src="excellentexport.js"></script>

<table id="ExcelTable">
  <tr>
    <td style="color:red">Column 1</td>
    <td style="color:blue">Column 2</td>
    <td style="color:green; font-weight:bold">Column 3</td>
  </tr>
  <tr style="color: purple">
    <td>400</td>
    <td>500</td>
    <td>600</td>
  </tr>
</table>

<a download="myFile.xls" href="#" onclick="return ExcellentExport.excel(this, 'ExcelTable', 'Sheet1');">Export to Excel</a>
