Sort the table

There’s a table:

Name	Surname	Age
John	Smith	10
Pete	Brown	15
Ann	Lee	5
...	...	...

There may be more rows in it.

Write the code to sort it by the "name" column.

Open a sandbox for the task.

The solution is short, yet may look a bit tricky, so here I provide it with extensive comments:

          let sortedRows = Array.from(table.rows)
  .slice(1)
  .sort((rowA, rowB) => rowA.cells[0].innerHTML > rowB.cells[0].innerHTML ? 1 : -1);

table.tBodies[0].append(...sortedRows);
        

Get all <tr>, like table.querySelectorAll('tr'), then make an array from them, cause we need array methods.
The first TR (table.rows[0]) is actually a table header, so we take the rest by .slice(1).
Then sort them comparing by the content of the first <td> (the name field).
Now insert nodes in the right order by .append(...sortedRows).

Tables always have an implicit element, so we need to take it and insert into it: a simple table.append(...) would fail.

Please note: we don’t have to remove them, just “re-insert”, they leave the old place automatically.

Open the solution in a sandbox.
