主要代码:

    //选中列，所有列，表名
    toggleSelection(selectRows, totalRows, tablename) {
      this.$refs.table.clearSelection();
      if (selectRows.length > 0) {
        this.$nextTick(() => {
          selectRows.forEach(item => {
            totalRows.forEach(item1 => {
              if (item.userId == item1.userId) {
                this.$refs.table.toggleRowSelection(item1);
              }
            });
          });
        });
      }
    },
