Luckysheet ,一款纯前端类似excel的在线表格,功能强大、配置简单、完全开源。

在线Demo:Luckysheet
elementUI中使用:
luckysheet 在 elementUI 的 dialog 中菜单和编辑框被遮罩,需要设置以下样式:
.luckysheet-cols-menu{
z-index: 9004 !important;
}
.luckysheet-input-box{
z-index: 3000 !important;
}
.luckysheet-wa-editor{
z-index: 2005 !important;
}
.luckysheet-modal-dialog-slider{
z-index: 2005 !important;
}
自定义鼠标右键菜单:
options: {
cellRightClickConfig: {
customs: [
//自定义右键菜单
{
title: "自定义菜单",
onClick: (clickEvent, event, params) => {
console.log(params);
},
},
.
.
.
],
},
},
公式触发:
forceCalculation 作用为初始化表格时强制刷新公式。如果公式较多会有性能问题,目前测试千条公式渲染大概1~2s,公式不多可以用。
options:{
forceCalculation:true,//强制刷新公式
}
设置单元格公式:
单元格的公式属性为 f,若无公式不要添加 f 属性,或者给 f 赋值null,其它值可能有奇怪问题
{
"r": 36,
"c": 6,
"v": {
"v": 1,
"m": "1",
"f": "=SUM(A1:A2)",//无值给null,其它值可能会有奇怪问题
}
}
如果单元格有公式,必须添加对应公式链 calcChain
{
"r": 6, //行数
"c": 3, //列数
"index": 1, //工作表id
//"func": [true, 23.75, "=AVERAGE(D3:D6)"], //公式信息,包含公式计算结果和公式字符串
"color": "w", //"w":采用深度优先算法 "b":普通计算
"parent": null,
"chidren": {},
"times": 0
}
设置单元格跳转sheet:
需要设置工作表配置中的 hyperlink。(或者可以参考下数据透视表 pivotTable)
options:{
data:[{
hyperlink:{
'1_1':{
linkType: 'external', //链接类型 external外部链接,internal内部链接
linkAddress: 'sheet名称!A2', //链接地址 网页地址或工作表单元格引用
linkTooltip: '提示', //提示
},
...
}
}]
}
工作表保护:
options:{
data:[{
config:{
authority:{// 当前工作表的权限配置
sheet: 1, // sheet表下标。
hintText: "这部分不可以进行修改", // 弹窗提示的文字
allowRangeList: [
{ sqref: '$A$2:$D$6' },//设置A2~D6为可编辑区域,其它区域不可编辑
...
],
}//工作表保护
}
}]
}
初始化含合并单元格:
options:{
data:[{
config:{
merge:{
'0_0':{
r:0,
c:0,
rs:2,//合并行数
cs:1 //合并列数
},
...
}// 合并单元格配置
}
}]
}

引入依赖:
import LuckyExcel from 'luckyexcel';
import { exportExcel } from './export';
导入本地Excel:
//导入本地文件
loadExcel(evt) {
const files = evt.target.files;
if (files == null || files.length == 0) {
alert("请选择文件");
return;
}
//获取文件名
let name = files[0].name;
//获取文件后缀
let suffixArr = name.split("."),
suffix = suffixArr[suffixArr.length - 1];
if (suffix != "xlsx") {
alert("目前只能导入xlsx类型的文件");
return;
}
//转换数据
LuckyExcel.transformExcelToLucky(
files[0],
function (exportJson, luckysheetfile) {
if (exportJson.sheets == null || exportJson.sheets.length == 0) {
alert("无法读取excel文件的内容,当前不支持xls文件!");
return;
}
console.log("exportJson", exportJson);
console.log("luckysheetfile",luckysheetfile)
jsonData.value = exportJson;
window.luckysheet.destroy();
window.luckysheet.create({
container: "luckysheet", //luckysheet is the container id
showinfobar: false,
data: exportJson.sheets,
title: exportJson.info.name,
userInfo: exportJson.info.name.creator,
});
}
);
},
导出Excel:
//第2个参数是导出的文件名
exportExcel(window.luckysheet.getAllSheets(), 'Excel文件名称');
添加单元格扩展属性:
在luckysheet源码中,/src/global/setdata.js 文件中修改 setcellvalue 方法
function setcellvalue(r, c, d, v) {
if(d == null){
d = Store.flowdata;
}
// 若采用深拷贝,初始化时的单元格属性丢失
// let cell = $.extend(true, {}, d[r][c]);
let cell = d[r][c];
let vupdate;
if(getObjType(v) == "object"){
if(cell == null){
cell = v;
}
else{
if(v.f != null){
cell.f = v.f;
}else if(cell.hasOwnProperty('f')){
delete cell.f;
}
if(v.spl != null){
cell.spl = v.spl;
}
if(v.ct != null){
cell.ct = v.ct;
}
// 添加扩展属性
if(v.expand != null){
cell.expand = v.expand
}
}
...
}
去掉工作表保护区弹窗:
在luckysheet源码的 /src/global/protection.js 文件中
// 注释掉所有
// tooltip.info("", ht);
