Angular 如何在Primeng中实现自定义排序

您可以提取数值，然后当值包含SUN时进行比较.请判断以下代码.

  sortTableData(event) {
    console.log(event);
    event.data.sort((data1, data2) => {
      let value1 = data1[event.field];
      let value2 = data2[event.field];
      let result = null;
      if (value1 == null && value2 != null) {
        result = -1;
      } else if (value1 != null && value2 == null) {
        result = 1;
      } else if (value1 == null && value2 == null) {
        result = 0;
      } else if (typeof value1 === 'string' && typeof value2 === 'string') {
        if (value1.includes('SUN') && value2.includes('SUN')) {
          const leftSplit = value1.split(' - ');
          const rightSplit = value2.split(' - ');
          const left = leftSplit.length ? +leftSplit[1] : 0,
            right = rightSplit.length ? +rightSplit[1] : 0;
          result = left < right ? -1 : left > right ? 1 : 0;
        } else {
          result = value1.localeCompare(value2);
        }
      } else {
        result = value1.localeCompare(value2);
      }
      return event.order * result;
    });
  }
