【问题描述】：
编辑 - 解决方案：
好的，我的问题的解决方案非常简单。如果您查看我的workbook.xml.rels 输出，您会注意到 rId2 已被工作簿的样式使用。解决方案非常简单：不要将 rId2 用于任何新工作表。经过简单的更改后，我的 excel 输出加载得很好。
我在函数中添加了一些 cmets 来反映这一点。
非常感谢@andrewjames，他的解决方案帮助我找到了这个错误。
问题：
我正在使用 jquery 数据表来呈现报告。当用户将报告输出到 excel 时，我想使用自定义函数 (generate_excel_sheet) 将 N 个工作表附加到输出中。
当前解决方案：
我有一个函数可以让我动态地将新工作表添加到我的 excel 输出中：
/**
* Builds a new excel sheet and attaches it to the current workbook
* @param {Object} xlsx - The excel workbook
* @param {Number} id - The id to be associated with the new sheet
* @param {string} name - The name to be associated with the new sheet
* @param {Array} data - The data to be inserted into the new sheet
*/
let generate_excel_sheet = (xlsx, id, name, data) => {
// helper function for generating column identifier letters (A, AA, AB, etc)
function colName(n) {
var ordA = 'a'.charCodeAt(0);
var ordZ = 'z'.charCodeAt(0);
var len = ordZ - ordA + 1;
var s = "";
while(n >= 0) {
s = String.fromCharCode(n % len + ordA) + s;
n = Math.floor(n / len) - 1;
}
return s.toUpperCase();
}
// Add sheet to [Content_Types].xml => <Types>
var source = xlsx['[Content_Types].xml'].getElementsByTagName('Override')[1];
var clone = source.cloneNode(true);
clone.setAttribute('PartName',`/xl/worksheets/${name}.xml`);
xlsx['[Content_Types].xml'].getElementsByTagName('Types')[0].appendChild(clone);
// Add sheet relationship to xl/_rels/workbook.xml.rels => Relationships
var source = xlsx.xl._rels['workbook.xml.rels'].getElementsByTagName('Relationship')[0];
var clone = source.cloneNode(true);
clone.setAttribute('Id',`rId${id}`); // CANNOT USE rId2, see solution
clone.setAttribute('Target',`worksheets/${name}.xml`);
xlsx.xl._rels['workbook.xml.rels'].getElementsByTagName('Relationships')[0].appendChild(clone);
// Add new sheet to xl/workbook.xml => <workbook><sheets>
var source = xlsx.xl['workbook.xml'].getElementsByTagName('sheet')[0];
var clone = source.cloneNode(true);
clone.setAttribute('name',name);
clone.setAttribute('sheetId',`${id}`);
clone.setAttribute('r:id',`rId${id}`); // CANNOT USE rId2, see solution
xlsx.xl['workbook.xml'].getElementsByTagName('sheets')[0].appendChild(clone);
// build out the following from data:
// * <row> for each row
// * <c> for each item in each row
var body = '';
for (i = 0; i < data.length; i++) {
body += `<row r="${i+1}">`;
for (j = 0; j < data[i].length; j++) {
body +=
`<c r="${colName(j)}${i+1}" t="inlineStr">` +
`<is>` +
`<t>${data[i][j]}</t>` +
`</is>` +
`</c>`
}
body += `</row>`;
}
// build <col> elements for each column in data
var columns = '';
for (i = 0; i < data[0].length; i++) {
columns += `<col customWidth="1" width="14.850000000000001" min="${i+1}" max="${i+1}" />`;
}
// build the sheet to be appended to the workbook
var newSheet =
'<?xml version="1.0" encoding="UTF-8" standalone="yes"?>'+
'<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:x14ac="http://schemas.microsoft.com/office/spreadsheetml/2009/9/ac" mc:Ignorable="x14ac">'+
'<cols>' +
columns +
'</cols>' +
'<sheetData>' +
body +
'</sheetData>' +
'</worksheet>';
// Add sheet to xl/worksheets
xlsx.xl.worksheets[`${name}.xml`] = $.parseXML(newSheet);
}
然后，当我构建我的数据表时，我使用以下代码来构建我的 excel 按钮：
buttons: [
'copy',
{
extend: 'excelHtml5',
title: rpt_title,
messageTop: rpt_message,
customize: function(xlsx) {
generate_excel_sheet(xlsx, 2, "test", [
["test1", 123],
["test2", 456],
["test3", 789],
]);
}
}
],

从这里 excel 给出和错误说工作簿需要修复。修复完成后，表测试为空白（无数据）并生成以下消息和日志文件：

@StackSlave 感谢您的提示。无法为此使用 CSV，因为输出需要易于我们的最终用户使用。我最终解决了问题，您可以在我对问题的编辑中看到解决方案。
