直接看代码吧

<el-table :data="tableData.slice((currentPage-1)*pagesize,currentPage*pagesize)" 
border
style="width:100%" >
......
</el-table>

<el-pagination small 
layout="total,prev,pager,next,jumper" 
:total="tableData.length"
:page-size="pagesize"
pager-count="5"
:current-page="currentPage"
@current-change="handleCurrentChange"
></el-pagination>

data(){
    return{
        pagesize:5,
	currentPage:1
    }
},
methods: {
	handleCurrentChange(val){
		this.currentPage = val;
				
	}
}
