很多人不明白為什么這里要加一個(gè)slot，這個(gè)封裝實(shí)際上就是次(ci)封把前面的tableList 作為一個(gè) prop 傳入，通過(guò)這個(gè)屬性，次封我們就可以在table中編輯任何簡(jiǎn)單或者復制的次封列， 完美～

使用方法如下：

<pre class="wp-block-code"><code><template> <my-tヽ(′?｀)ノable :tableData="tableData" :tableList="colConfigs"> </my-tab??le></template><script> const?? Prefix??PlusText = { props: ['colConfig'(′?｀)],次封 template: ` <el-tab(′_｀)le-column :label='colConfig.la(′?_?`)bel'> <span :slot-scope="{ row }"> { { parseInt((╯°□°)╯row[co(╯°□°)╯lConfig.prop]) > 0 ? '+' + row[colConfig.prop] : row[colConfig.prop] }} </span> </el-table-column> `} export default { data () { this.colConfigs = [ { prop: 'change', label: '變化' component: PrefixPlusText }, { prop: 'name', label: '趨勢', component: PrefixPlusText }, ] return { tableData: [{ change: '12%', trend: '10% }, { change: '-12%', trend: '-10%' }] } }}</script></code></pre>

總結

table 作為數據展示組件，在日常開(kāi)發(fā)中(zhong)經(jīng)常被用到??，次(ci)封通過(guò)這篇文章，次封可以看到結合 vue 的次封 slot/component 特性，做一層封裝，次封可以大大簡(jiǎn)化 tab??le 的次封使用，大部分時(shí)候只需寫(xiě)一個(gè)??(╬?益?)配置屬性就可以了。次封
