VUE项目中实现表格导出EXCEL表格

一步步照着做实现前端导出表格

第一：安装依赖

npm install -S file-saver xlsx
npm install -D script-loader

第二：在目录里新建excel文件夹

并且在excel文件夹里新建两个js文件（Blob.js和Export2Excel.js）

网站上下载这俩个我看到都是付费的，所以下边附代码：

Blob.js

}(typeof self !== "undefined" && self || typeof window !== "undefined" && window || this.content || this));

Export2Excel.js：

/* eslint-disable */
require('script-loader!file-saver');
require('./Blob');
require('script-loader!xlsx/dist/xlsx.core.min');
function generateArray(table) {var out = [];var rows = table.querySelectorAll('tr');var ranges = [];for (var R = 0; R < rows.length; ++R) {var outRow = [];var row = rows[R];var columns = row.querySelectorAll('td');for (var C = 0; C < columns.length; ++C) {var cell = columns[C];var colspan = cell.getAttribute('colspan');var rowspan = cell.getAttribute('rowspan');var cellValue = cell.innerText;if (cellValue !== "" && cellValue == +cellValue) cellValue = +cellValue;//Skip rangesranges.forEach(function (range) {if (R >= range.s.r && R <= range.e.r && outRow.length >= range.s.c && outRow.length <= range.e.c) {for (var i = 0; i <= range.e.c - range.s.c; ++i) outRow.push(null);}});//Handle Row Spanif (rowspan || colspan) {rowspan = rowspan || 1;colspan = colspan || 1;ranges.push({s: {r: R, c: outRow.length}, e: {r: R + rowspan - 1, c: outRow.length + colspan - 1}});};//Handle ValueoutRow.push(cellValue !== "" ? cellValue : null);//Handle Colspanif (colspan) for (var k = 0; k < colspan - 1; ++k) outRow.push(null);}out.push(outRow);}return [out, ranges];
};function datenum(v, date1904) {if (date1904) v += 1462;var epoch = Date.parse(v);return (epoch - new Date(Date.UTC(1899, 11, 30))) / (24 * 60 * 60 * 1000);
}function sheet_from_array_of_arrays(data, opts) {var ws = {};var range = {s: {c: 10000000, r: 10000000}, e: {c: 0, r: 0}};for (var R = 0; R != data.length; ++R) {for (var C = 0; C != data[R].length; ++C) {if (range.s.r > R) range.s.r = R;if (range.s.c > C) range.s.c = C;if (range.e.r < R) range.e.r = R;if (range.e.c < C) range.e.c = C;var cell = {v: data[R][C]};if (cell.v == null) continue;var cell_ref = XLSX.utils.encode_cell({c: C, r: R});if (typeof cell.v === 'number') cell.t = 'n';else if (typeof cell.v === 'boolean') cell.t = 'b';else if (cell.v instanceof Date) {cell.t = 'n';cell.z = XLSX.SSF._table[14];cell.v = datenum(cell.v);}else cell.t = 's';ws[cell_ref] = cell;}}if (range.s.c < 10000000) ws['!ref'] = XLSX.utils.encode_range(range);return ws;
}function Workbook() {if (!(this instanceof Workbook)) return new Workbook();this.SheetNames = [];this.Sheets = {};
}function s2ab(s) {var buf = new ArrayBuffer(s.length);var view = new Uint8Array(buf);for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;return buf;
}export function export_table_to_excel(id) {var theTable = document.getElementById(id);console.log('a')var oo = generateArray(theTable);var ranges = oo[1];/* original data */var data = oo[0];var ws_name = "SheetJS";console.log(data);var wb = new Workbook(), ws = sheet_from_array_of_arrays(data);/* add ranges to worksheet */// ws['!cols'] = ['apple', 'banan'];ws['!merges'] = ranges;/* add worksheet to workbook */wb.SheetNames.push(ws_name);wb.Sheets[ws_name] = ws;var wbout = XLSX.write(wb, {bookType: 'xlsx', bookSST: false, type: 'binary'});saveAs(new Blob([s2ab(wbout)], {type: "application/octet-stream"}), "test.xlsx")
}function formatJson(jsonData) {console.log(jsonData)
}
export function export_json_to_excel(th, jsonData, defaultTitle) {/* original data */var data = jsonData;data.unshift(th);var ws_name = "SheetJS";var wb = new Workbook(), ws = sheet_from_array_of_arrays(data);/* add worksheet to workbook */wb.SheetNames.push(ws_name);wb.Sheets[ws_name] = ws;var wbout = XLSX.write(wb, {bookType: 'xlsx', bookSST: false, type: 'binary'});var title = defaultTitle || '列表'saveAs(new Blob([s2ab(wbout)], {type: "application/octet-stream"}), title + ".xlsx")
}

第三：在common文件夹里新建js文件夹再新建util.js

util.js：

export function export2Excel(columns,list){require.ensure([], () => {const { export_json_to_excel } = require('../../excel/Export2Excel');let tHeader = []let filterVal = []console.log(columns)if(!columns){return;}columns.forEach(item =>{tHeader.push(item.title)filterVal.push(item.key)})const data = list.map(v => filterVal.map(j => v[j]))export_json_to_excel(tHeader, data, '数据列表');})
}

第四：在需要的页面import引入

import { export2Excel } from '../../common/js/util'

第五：表头初始化

第六：点击导出

补充会出现的问题ps:
在项目中用了eslint校验的，在第四步导入之后如果下边不用，页面会报错，
如下：（页面中用了就不会报错了，或者把exlint去掉）
