el-table实现翻页选择和回看

html

<el-table
	...
	<!-- row-key的row.id是你的行唯一标识，一般用id，翻页选的关键 -->
	:row-key="row => row.id"
	<!-- selection-change选择后的回调函数 -->
	@selection-change="selectionChange"
>
	<el-table-column
		...
		<!-- 选择框 -->
		type="selection"
		<!-- 回显的关键 -->
		reserve-selection
	>
	</el-table-column>
</el-table>

js

	data(){
		selectedList: [],
	}
	
	methods: {
		//  选择后的回调函数
		selectionChange(selection){
			this.selectedList = []
			selection.forEach(val => {
				this.selectedList.push(val.id)
			})
		}
	}
