vxe-table 筛选渲染filter-render 自定义组件
3.1在main.js文字中导入vxetableRenderer.js文件。1.创建vxetableRenderer.js文件。2.创建filterModal.vue文件。3.2在你的列配置中使用。

实现效果
实现步骤:
1.创建vxetableRenderer.js文件
import VXETable from 'vxe-table';
import filterModal from '@/components/render/filterModal.vue';
VXETable.renderer.add('MLFilterRender', {
renderFilter (h, renderOpts, params) {
return <filterModal params={ params }></filterModal>
},
//是否显示底部按钮，使用自定义的按钮
showFilterFooter:false,
// 筛选数据方法
filterMethod (params) {
const { option, row, column } = params
const { vals } = option.data
const cellValue = row[column.field];
return vals.includes(String(cellValue));
},
// 重置数据方法
filterResetMethod (params) {
const { options } = params
options.forEach((option) => {
option.data = {vals:[],sVal:'',operator1:"空白",value1:"",operator2:"空白",value2:"",concat:"与"}
})
},
})2.创建filterModal.vue文件

</style>3.使用自定义渲染
3.1在main.js文字中导入vxetableRenderer.js文件。
//我的是创建在根目录的config下,所以@/config/vxetableRenderer.js
import '@/config/vxetableRenderer.js';3.2在你的列配置中使用
//editRender对象中,name为渲染器名字,events为事件
methods:{
init(){
let columns=[
{width:80,field:"id",title:"id",params:{inputModal:false},filterRender:{name:"MLFilterRender"},filters:[{data:{type:col.Type,vals:[],sVal:'',operator1:"空白",value1:"",operator2:"空白",value2:"",concat:"与"}}]},
{width:80,field:"name",title:"姓名",params:{inputModal:true},filterRender:{name:"MLFilterRender"}},filters:[{data:{type:col.Type,vals:[],sVal:'',operator1:"空白",value1:"",operator2:"空白",value2:"",concat:"与"}}]
];
this.$refs.xGrid.loadColumn(columns);
},
}
