How to sort rows in a table using JavaScript?

Since JavaScript doesn’t provide any inbuilt functions to sort a table we will be required to use native methods to sort a given table. We will look into the methods in this article.

Approach:
A basic algorithm and similar approach will be used for both of the following examples. Loop the program to switch and sort the elements until it is sorted.

// executes on action like button click
Function() {   
   // main loop that runs until table is sorted
   While (condition = true) {   
      // runs for all rows
      for (i = 1; i < row.length; i++ ) {   
         // check if switch is required
         if (element_A > element_B){   
            // perform switch
            PerformSwitch();   
         }
      }
   }
}

Example 1: This example sorts the table using a while loop to switch the rows until the rows are sorted.

Output before click:

Output after click:

Example 2: This example sorts the table using the same loop technique but executes the function for both the given columns, as well as in both directions (ascending and descending).

Output before sort

Output for 1st column sort(ascending):

Output for 2nd column sort(descending):
