While I was working on some web app using DataTables, I came across with the following error

DataTables warning: table id=k_table_1 – Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3

https://datatables.net/manual/tech-notes/3

The solution was to normalize the id for the table.
Where I had k_table_1 now I have ktable1.
