vxe-table 列宽拖拽模式设置，自适应列宽，固定列宽

在使用 vxe-table 是，常用的列宽拖拽调整功能，通过列宽调整可以让用户灵活的自定义列宽。两种拖拽调整列宽模式分别用于不同场景。

动态列宽分配模式

调整列宽之后，对于未设置列宽的列会重新动态分配剩余宽度

<template>   <div>     <vxe-grid v-bind="gridOptions"></vxe-grid>   </div> </template>  <script> export default {   data () {     const gridOptions = {       border: true,       columnConfig: {         resizable: true       },       columns: [         { type: 'seq', width: 70 },         { field: 'name', title: 'Name' },         { field: 'sex', title: '最小列宽', minWidth: '20%' },         { field: 'age', title: 'Age' },         { field: 'time', title: 'Time' },         { field: 'address', title: 'Address' }       ],       data: [         { id: 10001, name: 'Test1', role: 'Develop', sex: 'Man', age: 28, address: 'test abc' },         { id: 10002, name: 'Test2', role: 'Test', sex: 'Women', age: 22, address: 'Guangzhou' },         { id: 10003, name: 'Test3', role: 'PM', sex: 'Man', age: 32, address: 'Shanghai' },         { id: 10004, name: 'Test4', role: 'Designer', sex: 'Women', age: 24, address: 'Shanghai' }       ]     }     return {       gridOptions     }   } } </script> 

列宽固定拖拽模式

通过设置 resizable-config.dragMode='fixed' 属性启用固定宽度模式；
在该模式下拖拽列宽之后将会始终保持和界面看到的列宽完全一致，不会再重新动态分配剩余列宽

<template>   <div>     <vxe-grid v-bind="gridOptions"></vxe-grid>   </div> </template>  <script> export default {   data () {     const gridOptions = {       border: true,       columnConfig: {         resizable: true       },       resizableConfig: {         dragMode: 'fixed'       },       columns: [         { type: 'seq', width: 70 },         { field: 'name', title: 'Name' },         { field: 'sex', title: '最小列宽', minWidth: '20%' },         { field: 'age', title: 'Age' },         { field: 'time', title: 'Time' },         { field: 'address', title: 'Address' }       ],       data: [         { id: 10001, name: 'Test1', role: 'Develop', sex: 'Man', age: 28, address: 'test abc' },         { id: 10002, name: 'Test2', role: 'Test', sex: 'Women', age: 22, address: 'Guangzhou' },         { id: 10003, name: 'Test3', role: 'PM', sex: 'Man', age: 32, address: 'Shanghai' },         { id: 10004, name: 'Test4', role: 'Designer', sex: 'Women', age: 24, address: 'Shanghai' }       ]     }     return {       gridOptions     }   } } </script>
