please help me...thank you in advance

Answer 1

Instead of:
<th>#sortablelink('Student ID Number')</th>
Use this: <th>#sortablelink('id','Student ID Number')</th>
The first parameter of #sortablelink should be the column name in your database and the second parameter should be the name by which you want to display the column.
Do the same for all the table headings too.
Also, you need to add the following statement at the end of your table tag:-
</table>
{!! $students->appends(\Request::except('page'))->render() !!}
Here, div is not required.
