# el-bigdata-table
|
|||
|
|
|
|||
|
|
用来实现el-table展示大数据
|
|||
|
|
流畅渲染万级数据并不会影响到el-table的原有功能
|
|||
|
|
|
|||
|
|
[点击查看在线demo](https://code-farmer-i.github.io/el-bigdata-table/dist/)
|
|||
|
|
|
|||
|
|
## Install
|
|||
|
|
```shell
|
|||
|
|
npm install el-bigdata-table -S
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## webpack.base.conf.js
|
|||
|
|
因代码中使用了es6的语法 所以需要添加babel配置
|
|||
|
|
``` javascript
|
|||
|
|
'use strict'
|
|||
|
|
const path = require('path')
|
|||
|
|
const utils = require('./utils')
|
|||
|
|
const config = require('../config')
|
|||
|
|
const vueLoaderConfig = require('./vue-loader.conf')
|
|||
|
|
// 此处为添加的配置
|
|||
|
|
const fs = require('fs')
|
|||
|
|
|
|||
|
|
function resolve (dir) {
|
|||
|
|
return path.join(__dirname, '..', dir)
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
//此处为添加的配置
|
|||
|
|
let dirsName = fs.readdirSync(resolve('node_modules')).filter(dirName => /el-bigdata-table/.test(dirName))
|
|||
|
|
const includesDirs = dirsName.map(dir => resolve(`node_modules/${dir}/src`))
|
|||
|
|
|
|||
|
|
module.exports = {
|
|||
|
|
... //省略的代码
|
|||
|
|
module: {
|
|||
|
|
rules: [
|
|||
|
|
// 省略代码...
|
|||
|
|
// 此处有添加babel-loader配置 ‘...includesDirs‘
|
|||
|
|
{
|
|||
|
|
test: /.js$/,
|
|||
|
|
loader: 'babel-loader',
|
|||
|
|
include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client'), ...includesDirs]
|
|||
|
|
},
|
|||
|
|
{
|
|||
|
|
test: /.(png|jpe?g|gif|svg)(?.*)?$/,
|
|||
|
|
loader: 'url-loader',
|
|||
|
|
options: {
|
|||
|
|
limit: 10000,
|
|||
|
|
name: utils.assetsPath('img/[name].[hash:7].[ext]')
|
|||
|
|
}
|
|||
|
|
},
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Quick Start
|
|||
|
|
``` javascript
|
|||
|
|
// main.js
|
|||
|
|
import 'el-bigdata-table'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 基础用法
|
|||
|
|
```html
|
|||
|
|
<template>
|
|||
|
|
<!-- 使用 useVirtual 属性开启虚拟滚动 使用虚拟滚动时，必须要固定表格高度和行高 -->
|
|||
|
|
<el-table
|
|||
|
|
:data="tableData"
|
|||
|
|
height="400"
|
|||
|
|
useVirtual
|
|||
|
|
>
|
|||
|
|
<el-table-column
|
|||
|
|
type="index"
|
|||
|
|
width="100"
|
|||
|
|
fixed
|
|||
|
|
></el-table-column>
|
|||
|
|
<el-table-column
|
|||
|

prop="date"
|
|||
|
|
label="日期"
|
|||
|
|
width="180">
|

|
|
</el-table-column>
|
|||
|
|
<el-table-column
|
|||
|
|
prop="name"
|
|||
|
|
label="姓名"
|
|||
|
|
width="180">
|
|||
|
|
</el-table-column>
|
|||
|
|
<el-table-column
|
|||
|
|
prop="address"
|
|||
|
|
label="地址">
|
|||
|
|
</el-table-column>
|
|||
|
|
</el-table>
|
|||
|
|
</template>
|
|||
|
|
|
|||
|
|
<script>
|
|||
|
|
export default {
|
|||
|
|
data() {
|
|||
|
|
return {
|
|||
|
|
tableData: Array.from({length: 10000}, () => ({
|
|||
|
|
date: '2016-05-03',
|
|||
|
|
name: '王小虎',
|
|||
|
|
address: '上海市普陀区金沙江路 1516 弄'
|
|||
|
|
}))
|
|||
|

|
|||
|
|
}

|
|
row-height | 行高(必须要设置正确的行高，否则会导致表格计算不正确) | Number | 48
|
|||
|
|
excess-rows | 表格可视区域上方与下方额外渲染的行数，行数越多表格接替渲染效果越好，但越耗性能 | Number | 5
