mounted() {
console.log(this.tableData);
this.$axios.get("/datatable.json").then((res, rej) => {

});
},
methods: {
handleSelectionChange(val) {
this.multipleSelection = val;
console.log(val);
},
handleSizeChange(val) {

这里tableData是从后台获取的数据，在计算属性上定义通过this.tableList赋值，这里Input赋值关键字查询，分页的当前页通过handleCurrentChange方法获取，分页的每页显示个数选择器通过handleSizeChange来获取，这里tableData通过tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)方式来获取
