Question

What is the best way to organize information in a table based on the date

This is my data table

https://i.stack.imgur.com/1DNlj.png in the displayed table, the registration dates are sorted with the oldest date at the top. However, I aim to have the newest data displayed first.

Below is the code snippet I am using:

this.dataSource = [];
    this.dataSource = this.dataSource.sort((a, b) => {
      if (a.createdAt > b.createdAt) {
          return 1;
        }
      if (a.createdAt < b.createdAt) {
          return -1;
        }
      return 0;

    });

The field createdAt contains string values.

Answer №1

The sorting code provided needs to be updated for accuracy. Here is the corrected version:

this.dataList = [];
    this.dataList = this.dataList.sort((x, y) => {
      var output = 0;
      if (x.createdTime > y.createdTime) {
          output = 1;
      } else {
          output = -1;
      }
      return output;
    });

@Rence Sacramento createdAt could refer to either a timestamp or date string in this context. It is worth noting that there are two separate variables named "DataSource" and "dataSource".

this.DataSource = [];  
    this.DataSource = this.dataSource.sort((a, b) => {
      return new Date(a.createdAt) - new Date(b.createdAt); // Sorting ASC order by createdAt
    });
