TypeError: c is undefined

I don\'t know what is wrong with my code as I can s

Answer 1

Sometime, This type issue arrives by fixing mismatched / unequal columns with HTML and datatables columns.

"columns": [
        null,
        null,
        null,
        {"orderable": false, "width":"2%"},
    ],

Above javascript defined 4 columns and HTML having 5 columns

   A
   B
   C
   D
   E

Hence you will have to fix / equal both side HTMl and Datatable configuration.

"columns": [
        null,
        null,
        null,
        null, //Added New
        {"orderable": false, "width":"2%"},
    ],
