手写OOXML文档——导出xlsx格式表格文档

一、准备工作：

2个js库，另外把样式文件抽离出来

require('file-saver');
import JSZip from 'jszip'
import {stylesData,theme1Data} from './xlsxStyles'

转换成OOXML文档：

新建“工作簿1.xlsx”，修改后缀.zip,得到如下目录结构：

内容、属性文档目录：content_Types

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
    <Default Extension="png" ContentType="image/png" />
    <Default Extension="rels" ContentType="application/vnd.openxmlformats-package.relationships+xml" />
    <Default Extension="xml" ContentType="application/xml" />

    <Override PartName="/docProps/app.xml" ContentType="application/vnd.openxmlformats-officedocument.extended-properties+xml" />
    <Override PartName="/docProps/core.xml" ContentType="application/vnd.openxmlformats-package.core-properties+xml" />

    <Override PartName="/xl/sharedStrings.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.sharedStrings+xml" /> //字符串存储共享文件
    <Override PartName="/xl/styles.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.styles+xml" />
    <Override PartName="/xl/theme/theme1.xml" ContentType="application/vnd.openxmlformats-officedocument.theme+xml" />
    <Override PartName="/xl/workbook.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml" />

    <Override PartName="/docProps/custom.xml" ContentType="application/vnd.openxmlformats-officedocument.custom-properties+xml" /> //自定义属性文档：如有样式设置
    
    <Override PartName="/xl/worksheets/sheet1.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" /> //遍历：纯数字数据文档或内嵌的字符串
    <Override PartName="/xl/worksheets/sheet2.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" />
    <Override PartName="/xl/worksheets/sheet3.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" />
    <Override PartName="/xl/worksheets/sheet4.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" />
    <Override PartName="/xl/worksheets/sheet5.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" />
    <Override PartName="/xl/worksheets/sheet6.xml" ContentType="application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml" />
    
    <Override PartName="/xl/drawings/drawing1.xml" ContentType="application/vnd.openxmlformats-officedocument.drawing+xml" /> //遍历：数据关联文档,如插入图片、表格
    <Override PartName="/xl/drawings/drawing2.xml" ContentType="application/vnd.openxmlformats-officedocument.drawing+xml" />
    <Override PartName="/xl/drawings/drawing3.xml" ContentType="application/vnd.openxmlformats-officedocument.drawing+xml" />
    <Override PartName="/xl/drawings/drawing4.xml" ContentType="application/vnd.openxmlformats-officedocument.drawing+xml" />
    <Override PartName="/xl/drawings/drawing5.xml" ContentType="application/vnd.openxmlformats-officedocument.drawing+xml" />
    <Override PartName="/xl/drawings/drawing6.xml" ContentType="application/vnd.openxmlformats-officedocument.drawing+xml" />
</Types>

   1.1关联文件：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
    <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml" />
    <Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml" />
    <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml" />
</Relationships>

复杂一点的：多个自定义custom.xml文件

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
    <Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/custom-properties" Target="docProps/custom.xml" />
　　...
</Relationships>

 多一个自定义xml文档:目测fmtid是随机生成的UUID

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Properties xmlns="http://schemas.openxmlformats.org/officeDocument/2006/custom-properties" xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes">
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="2" name="KSOProductBuildVer">
        <vt:lpwstr>2052-11.1.0.8976</vt:lpwstr>
    </property>
</Properties>

其他2个文件：

app.xml:分页sheet文档,如果是wps生成的信息没有那么全

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Properties xmlns="http://schemas.openxmlformats.org/officeDocument/2006/extended-properties" xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes">
    <Application>Microsoft Excel</Application>
    <DocSecurity>0</DocSecurity>
    <ScaleCrop>false</ScaleCrop>
    <HeadingPairs>
        <vt:vector size="2" baseType="variant">
            <vt:variant>
                <vt:lpstr>工作表</vt:lpstr>
            </vt:variant>
            <vt:variant>
                <vt:i4>6</vt:i4> //合计总数：6
            </vt:variant>
        </vt:vector>
    </HeadingPairs>
    <TitlesOfParts>
        <vt:vector size="6" baseType="lpstr"> //合计总数+遍历1-6
            <vt:lpstr>Sheet1</vt:lpstr>
            <vt:lpstr>Sheet2</vt:lpstr>
            <vt:lpstr>Sheet3</vt:lpstr>
            <vt:lpstr>Sheet4</vt:lpstr>
            <vt:lpstr>Sheet5</vt:lpstr>
            <vt:lpstr>Sheet6</vt:lpstr>
        </vt:vector>
    </TitlesOfParts>
    <Company></Company>
    <LinksUpToDate>false</LinksUpToDate>
    <SharedDoc>false</SharedDoc>
    <HyperlinksChanged>false</HyperlinksChanged>
    <AppVersion>16.0300</AppVersion>
</Properties>

固定格式的core.xml文档信息：如创建人、创建时间

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<cp:coreProperties xmlns:cp="http://schemas.openxmlformats.org/package/2006/metadata/core-properties" xmlns:dc="http://purl.org/dc/elements/1.1/"
 xmlns:dcterms="http://purl.org/dc/terms/" xmlns:dcmitype="http://purl.org/dc/dcmitype/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <dc:creator>zhangsan</dc:creator>
    <cp:lastModifiedBy>zhangsan</cp:lastModifiedBy>
    <dcterms:created xsi:type="dcterms:W3CDTF">2019-10-21T12:16:00Z</dcterms:created>
    <dcterms:modified xsi:type="dcterms:W3CDTF">2019-10-21T12:16:16Z</dcterms:modified>
</cp:coreProperties>

二、核心文件XL：

或

 内容不为空多出一个字符串共享文档：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<sst xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" count="841" uniqueCount="217">
    <si>
        <t>列1</t>
    </si>
</sst>

如果是数据不为空，会多出1个drawings文档；

 如果有图片，会多出一个media文档；

 如果插入表格，会多出一个tables文档。

图形信息使用base64格式存储

 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<table xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" id="1" name="表1" displayName="表1" ref="A1:U25"
 totalsRowShown="0">
    <tableColumns count="21">
        <tableColumn id="1" name="列1" dataDxfId="0" />
        <tableColumn id="2" name="列2" dataDxfId="1" />
        <tableColumn id="3" name="列3" dataDxfId="2" />
    </tableColumns>
    <tableStyleInfo name="TableStyleMedium2" showFirstColumn="0" showLastColumn="0" showRowStripes="1" showColumnStripes="0" />
</table>

其他：主题文件theme1.xml和外部样式文件styles.xml,数据可以抽离出来单独存放

三、数据输出：存储格式需要区分，并分开存储

/* eslint-disable */
require('file-saver');

import JSZip from 'jszip'
import {stylesData,theme1Data} from './xlsxStyles'

export function export_txt_to_zip(imgData, chartData ,xlsxName) {
    // console.log(imgData,"图形");
    // console.log(chartData ,"数据");
  const chartDataLen = chartData.length || 1
  const zip = new JSZip();
  const zip_name = xlsxName || 'excel文档';

    // 第一层文件夹：
    const _rels = zip.folder("_rels");
    const docProps = zip.folder("docProps");//app.xml core.xml custom.xml
    const xl = zip.folder("xl"); // sharedStrings.xml styles.xml workbook.xml

  // 第二层文件夹：
    const xl_rels = xl.folder("_rels");
    const media = xl.folder("media"); //图片2*6=12
    const theme = xl.folder("theme");// theme1.xml
    const drawings = xl.folder("drawings"); // 【1个关系文件夹+数据文件6个】
    const worksheets = xl.folder("worksheets"); // 【1个关系文件夹+数据文件6个】

    // 第三层文件夹：
    const drawings_xl_rels = drawings.folder("_rels");
    const sheets_xl_rels = worksheets.folder("_rels");//可以不需要关系文档
