Remove any applied sorting from the table within the code

Question

Remove any applied sorting from the table within the code

I've been attempting to remove the applied sorting on a table programmatically using the active and direction fields, but so far, I haven't been successful:

@ViewChild(MatSort) sort: MatSort;

private clearSort() {
    // Clear the active sort column
    this.sort.active = "";
    // Reset the sort direction
    this.sort.direction = "";
}

I've checked out the Sort Header Documentation, but unfortunately, I couldn't find any built-in method that allows for clearing an applied sort on a specific table.

If anyone has any advice on how to achieve this, I would greatly appreciate it.

To establish a default sorting option, you can utilize the sort function within the MatSort api.

defaultSort: MatSortable = {
    id: 'defColumnName',
    start: 'asc',
    disableClear: true
};

Next, implement the sort function using the MatSort directive:

this.sort.sort(this.defaultSort);
//set default sorting direction
this.sort.direction = 'asc';

Note that executing the above code will activate the sortChange event subscription.

To reset a sort, it is typically necessary to reapply the original sorting order that was initially used.

If the initial sort order does not contain a natural key, you may have to add an original order field in your dataset to allow for sorting by that field in order to "clear" any previous sorting that has taken place since loading the data.

Although I am unfamiliar with using MatSort, without confirmation from others, my assumption would be that to clear the sorting, one would need to follow the steps described above.

If the library provided a reset function, it would require keeping the data in its original order stored somewhere in memory, which is why many libraries opt not to include this feature.
