分页器/排序似乎已分配给表格，但更改页面/排序时数据不会改变

Question

想通了我会尝试咨询互联网，因为最近几天我一直试图弄清楚这一点无济于事。

我有一个MatDialog，在打开该对话框时，构造函数将调用一个函数，该函数进行两次HTTP调用以获取一些数据供我修改，然后放入表中。

函数如下：

// Get transaction summary from both runs
    this.http.get(this.data.epvURL + "TransactionsSummary" + "?timeOfData=" + this.run1.TimeOfData + "&timeOfInitiatedRun=" + this.run1.InitiatedRuntime, { withCredentials: true }).pipe(timeout(120000)).subscribe(data1 => {
      this.http.get(this.data.epvURL + "TransactionsSummary" + "?timeOfData=" + this.run2.TimeOfData + "&timeOfInitiatedRun=" + this.run2.InitiatedRuntime, { withCredentials: true }).pipe(timeout(120000)).subscribe(data2 => {
        var firstRun = data1 as any;
        var secondRun = data2 as any;

        // Prep table
        var comparison: ComparisonArray[] = [];
        for (let index = 0; index < firstRun.length; index++) {
          var max = Math.max(firstRun[index].AvgDur, secondRun[index].AvgDur);
          var min = Math.min(firstRun[index].AvgDur, secondRun[index].AvgDur);
          var diff: string = "";
          if (max != 0 && min != 0 && max != min) {
            diff = (((max - min) / Math.abs(min)) * 100).toFixed(2).toString() + "%";
          }

          // Default to first run being best performing
          var bestRun: number = 1;
          if (secondRun[index].AvgDur == min) {
            bestRun = 2;
          }

          var element: ComparisonArray = {
            ModuleName: firstRun[index].ModuleName,
            AvgDur1: firstRun[index].AvgDur,
            AvgDur2: secondRun[index].AvgDur,
            Difference: diff,
            BestRun: bestRun
          };
          comparison.push(element);
        }
        this.loadingSummary = false;
        this.dialogRef.updateSize("97%", "94%");
        this.comparisonData = new MatTableDataSource<ComparisonArray>(comparison as any);
      });
    });

在最后一行，您可以看到我将修改后的数据放入“ comparisonData”表中。函数完成后，将返回构造函数，然后运行以下代码：

setTimeout(() => {
        this.comparisonData.paginator = this.comparisonPaginator;
        this.comparisonData.filter = this.comparisonFilter;
        this.comparisonData.sort = this.comparisonSort;
      }, 100);

有人知道为什么每个页面选择的过滤器和项目都可以正常工作，但是排序和页面更改除了更新列标题和页面编号/项目计数上的“排序箭头”而没有实际显示“新”数据外没有其他作用吗？
