Vue+ant表格可拖动列宽
之前一直用的elementui组件库,el-table是可以拖动列宽的。但是最近新接触的ant组件库不行,必须要自己做些修改了,官网上面也给出了解决方案return{header{cellconst{col||!key{w10,x1,axis{dragging...dragProps})//此为局部注册//全局引入使用'vue-draggable-resizable'替换VueDraggableR

前言
之前一直用的elementui组件库,el-table是可以拖动列宽的。但是最近新接触的ant组件库不行,必须要自己做些修改了,官网上面也给出了解决方案: vue-draggable-resizable
一、安装vue-draggable-resizable插件
yarn add vue-draggable-resizable
二、全局引入组件或局部引入
在项目的main.js中全局引入
// 挂载全局使用的方法
import VueDraggableResizable from 'vue-draggable-resizable'
import 'vue-draggable-resizable/dist/VueDraggableResizable.css'
Vue.component('vue-draggable-resizable', VueDraggableResizable)
或者在页面中局部引入选其一
import VueDraggableResizable from 'vue-draggable-resizable'
import 'vue-draggable-resizable/dist/VueDraggableResizable.css'
三、在a-table中添加components属性
注意:一定要有bordered属性,columns必须有宽度width
四、定义components
handleDrag(column){
return {
header: {
cell: (h, props, children) => {
const { key, ...restProps } = props
const col = column.find((col) => {
const k = col.dataIndex || col.key
return k === key
})
if (!col || !col.width) {
return h('th', { ...restProps }, [...children])
}
const dragProps = {
key: col.dataIndex || col.key,
class: 'table-draggable-handle',
attrs: {
w: 10,
x: col.width,
z: 1,
axis: 'x',
draggable: true,
resizable: false,
},
on: {
dragging: (x, y) => {
col.width = Math.max(x, 1)
},
},
}
const drag = h(VueDraggableResizable, { ...dragProps }) //此为局部注册
//全局引入使用'vue-draggable-resizable'替换VueDraggableResizable
return h('th', { ...restProps, class: 'resize-table-th' }, [...children, drag])
},
}
}
}

注意:style不要加scoped作用域
<template>
<a-card :bordered="false">
<a-table
ref="table"
size="middle"
bordered
rowKey="id"
:columns="columns"
:dataSource="dataSource"
:components="handleDrag(columns)"
>
</a-table>
</a-card>
