for example, the table is sorted according to the date order before paging, and the date is sorted disorderly after paging, as shown in the following figure 
 this is the first page 
 
 
 
 obviously, the date order is out of order, but it is sorted on the current page, not the whole sort. 
 my code is as follows 
<template>
  <div>
    ...
          <div>
            <el-table
              :data="tableData.slice((currentPage-1)*pagesize,currentPage*pagesize)"
              border
              style="width: 100%"
              :default-sort = "{prop: "date", order: "descending"}">
              <el-table-column
                prop="date"
                label="Modified Date"
                width="180">
              </el-table-column>
              <el-table-column
                prop="name"
                label="Experiment Name"
                width="180">
              </el-table-column>
              <el-table-column
                prop="content"
                label="Content"
                width="640">
              </el-table-column>
            </el-table>
            <br><br>
            <div class="block">
              <el-pagination
                @size-change="handleSizeChange"
                @current-change="handleCurrentChange"
                :current-page="currentPage"
                :page-sizes="[10, 20, 30, 40]"
                :page-size="pagesize"
                layout="total, sizes, prev, pager, next, jumper"
                :total="tableData.length">
              </el-pagination>
            </div>
            </div>
...
</template>
<script>
...
    export default{
      data() {
        return {
          tableData:[{
            date: "",
            name: "",
            content: ""
          }],
          currentPage: 1,
          pagesize:10
        }
      },
      mounted: function(){
        this.getAbHistory();
      },
      methods:{
        handleSizeChange(size) {
          this.pagesize = size;
        },
        handleCurrentChange(currentPage) {
          this.currentPage = currentPage;
        },
        getAbHistory(){
          axios.get("/historyScan/AbHistory").then(result =>{
            var res = result.data;
            if(res.status == "0"){
              let values = res.result.hbaseRst;
              var data = []
              for (let i = 0; i < values.length; iPP){
                var obj = {}
                obj.name= values[i].key;
                obj.date = moment(values[i].timestamp).format("YYYY-MM-DD HH:mm:ss");
                obj.content = values[i].$;
                data[i] = obj
              }
              this.tableData = data;;
            }
            else{
              this.$message.error("A/B test ");
            }
          });
        }
      }
    }
</script>
Please give me some advice on how to sort the whole data and how to modify the front-end code. Thank you
