如何将多个 html 表格转换为具有多个工作表的 excel 工作表？你能帮忙解决这个问题吗？

我的例子https://jsfiddle.net/kdkd/5p22gdag/

        function tablesToExcel() 
        

            var tab_text = "<table border='2px'><tr bgcolor='#87AFC6'>";
            var textRange; var j = 0;
            tab = document.getElementById('tbl2'); // id of table


            for (j = 0 ; j < tab.rows.length ; j++) 
                tab_text = tab_text + tab.rows[j].innerHTML + "</tr>";
                //tab_text=tab_text+"</tr>";
            

            tab_text = tab_text + "</table>";
            var ua = window.navigator.userAgent;
            var msie = ua.indexOf("MSIE ");

            if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer
            
                txtArea1.document.open("txt/html", "replace");
                txtArea1.document.write(tab_text);
                txtArea1.document.close();
                txtArea1.focus();
                sa = txtArea1.document.execCommand("SaveAs", true, "Say Thanks to Sumit.xls");
            
            else                 //other browser not tested on IE 11
                sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));


            return (sa);

您是否检查过这些问题：***.com/questions/24636956/… 和 ***.com/questions/18234448/…？他们似乎对此有解决方案 谢谢。我已经检查了上面给出的链接。一个小问题是所有 HTML 表格都插入到一个工作表中。 （成功创建了多个工作表）但是， 这是您想要的示例..jsfiddle.net/qxLn3h86 我已经尝试过了，但我的表格有内联 CSS，所以它不起作用。请检查这个小提琴jsfiddle.net/kdkd/qxLn3h86/49 等待解决..请帮助 【参考方案1】：

我刚刚发布此内容是为了提供一个使用 css 导出多个工作表的更多选项。 Working Fiddle

我打了更多天，找到了这种方法。希望这对其他人有帮助。

我发现您的代码存在一个问题。尽管您可能会争辩说，也许我的源表不完全符合 HTML。 具体来说，我的表的定义类似于

    <table id="tbl1">
                                    <thead>
                                        <tr>
                                            <th>Name</th>
                                            <th>E-Mail</th>
                                            <th>Last<br>Login</th>
                                            <th>Suspended</th>
                                        </tr>
                                    </thead>
                                    <tbody>

                                            <tr>
                                                <td><a target="_new" href="https://xxxxx.zendesk.com/agent/users/378955944453">Joe User</a></td>
                                                <td>JUser@xyz.edu</td>
                                                <td>2020-02-18T16:42:50Z</td>
                                                <td>false</td>
                                            </tr>
                                        <tfoot>
                                                <tr>
                                                    <td><b>Totals: </b></td>
                                                    <td></td>
                                                    <td></td>
                                                    <td></td>
                                                </tr>
                                        </tfoot>
                                    </tbody>

    </table>

并且由于&lt;th&gt;Last&lt;br&gt;Login&lt;/th&gt; 中包含&lt;br&gt;，XML 解析表明它需要&lt;/br&gt;。但为什么 ？？？ HTML 并没有真正的&lt;/br&gt; 因此，虽然 XLS 会打开，但电子表格中没有数据，也没有定义任何工作表

但是一个合适的解决方法是改变你的 javascript 

dataValue = (dataValue)?dataValue:tables[i].rows[j].cells[k].innerHTML;

到

dataValue = (dataValue)?dataValue:tables[i].rows[j].cells[k].innerText;

【讨论】：

你不能在你的答案中解决另一个答案。如果您在现有答案中发现问题，您应该发布自己的完整答案。【参考方案3】：

对多张工作表使用下面的代码。我正在使用三个表格数据来生成 Excel。 导入库：

从“xlsx”导入*为XLSX；

static doExcel1(tableId1, tableId2, tableId3) 

    let targetTableElm1 = document.getElementById(tableId1);
    let targetTableElm2 = document.getElementById(tableId2);
    let targetTableElm3 = document.getElementById(tableId3);

    const wb =  SheetNames: [], Sheets:  ;
    var ws1 = XLSX.utils.table_to_book(targetTableElm1).Sheets.Sheet1;
    wb.SheetNames.push("Sheet1"); wb.Sheets["Sheet1"] = ws1;

    var ws2 = XLSX.utils.table_to_book(targetTableElm2).Sheets.Sheet1;
    wb.SheetNames.push("Sheet2"); wb.Sheets["Sheet2"] = ws2;

    var ws3 = XLSX.utils.table_to_book(targetTableElm3).Sheets.Sheet1;
    wb.SheetNames.push("Sheet3"); wb.Sheets["Sheet3"] = ws3;
    console.log(ws1); console.log(ws2); console.log(ws3); console.log(wb);
    const blob = new Blob([this.s2ab(XLSX.write(wb,  bookType: 'xlsx', type: 'binary' ))], 
      type: "application/octet-stream"
    );
    const link = document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    link.download = 'demo.xlsx';

    document.body.appendChild(link);

    link.click();

    document.body.removeChild(link);
  
  static s2ab(s) 
    const buf = new ArrayBuffer(s.length);
    const view = new Uint8Array(buf);
    for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
    return buf;

使用表 ID 调用：doExcel1("ExampleTable1","ExampleTable2","ExampleTable3");点击按钮。

注意：以上解决方案仅适用于 Angular，如果您想在节点或 js 中使用它，则需要进行一些更改。

【参考方案4】：

在互联网上没有找到任何东西来解决这个问题，所以我创建了自己的。这是一个创建 2 个或更多工作表（每个表 1 个工作表）并且工作正常的工作示例。享受！ :)

Run the example in https://jsfiddle.net/xvkt0yw9/

这是对 XLS 导出（网页）的 .mht 表示的~逆向工程。 工作表名称在每个表的 data-SheetName 属性中定义。 该函数可以很容易地转换为其他编程语言。 （基本上全是replace mes）

还为单元格编号格式提供内联样式（作为文本、常规、2 位小数）

注意：无论您是否设置选项，单元格网格都会显示... 警告 不要缩进 javascript 函数。 （我不知道如果你这样做，XLS 会发生什么，没有测试，没有必要） Html：（将以下内容放入 test.html 文件中并在浏览器中运行。单击按钮并打开导出的 Worksheet.xls）

Bhutani Vijay 的代码运行良好。为了兼容 IE 11，我使用了 Blob 对象，如下所示：

【参考方案6】：

Here 是一个更好的解决方案，它支持以最新的 Excel 格式导出表格，即 xlsx .如果在 Chrome 上导出的总行数超过 3407，则可接受的解决方案将失败。

上面链接中的一个例子： http://jsfiddle.net/6ckj281f/

html 

<button onclick="saveFile()">Save XLSX file</button>

javascript

window.saveFile = function saveFile () 
var data1 = [a:1,b:10,a:2,b:20];
var data2 = [a:100,b:10,a:200,b:20];
var opts = [sheetid:'One',header:true,sheetid:'Two',header:false];
var res = alasql('SELECT INTO XLSX("restest344b.xlsx",?) FROM ?',
                 [opts,[data1,data2]]);

哦，这正是我想要的。谢谢！【参考方案7】： 
function tablesToExcel() 
        

            var tab_text = document.getElementById("MsoNormalTable").outerHTML;
            var textRange; var j = 0;
            var tab = document.getElementById('MsoNormalTable'); // id of table
            var sa;

            var ua = window.navigator.userAgent;
            var msie = ua.indexOf("MSIE ");
            var txt = document.getElementById('txtArea1').contentWindow;
            if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer
            
                txt.document.open("txt/html", "replace");
                txt.document.write(tab_text);
                txt.document.close();
                txt.focus();
                sa = txt.document.execCommand("SaveAs", true, "Say Thanks to Sumit.xls");
            
            else                 //other browser not tested on IE 11
                sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));

            return (sa);
        
 

<iframe id="txtArea1" style="display:none"></iframe>

它可以在 IE7+ 上正常工作... :)
