How can I add columns to my HTML table from my JSON file

I am trying to put this JSON data into my html table using datatables jQuery plugin.

{
"status":{"1":"Debit","2":"Debit","3":"Debit","4":"Debit","5":"Debit","6":"Debit","7":"Debit"},
"funds code":{"1":"None","2":"None","3":"None","4":"None","5":"None","6":"None","7":"None"},
"amount":{"1":"-298.01 USD","2":"-4930 USD","3":"-8334 USD","4":"-366.18 USD","5":"-6.39 
            USD","6":"-5 USD","7":"-0.80 USD"},
"id":{"1":"NTRF","2":"NTRF","3":"NTRF","4":"NTRF","5":"NTRF","6":"NTRF","7":"NTRF"},
"customer reference": 
   {"1":434433,"2":434661,"3":434796,"4":435273,"5":435506,"6":435688,"7":435688},
"bank reference":{"1":"None","2":"None","3":"None","4":"None","5":"None","6":"None","7":"None"},
"extra details":{"1":"","2":"","3":"","4":"","5":"","6":"","7":""},
"currency":{"1":"USD","2":"USD","3":"USD","4":"USD","5":"USD","6":"USD","7":"USD"},
"date": 
{"1":1625270400000,"2":1625270400000,"3":1625270400000,"4":1625270400000,"5":1625270400000,"6":1625270400000,"7":1625270400000},

"entry date":{"1":"2021-07-03","2":"2021-07-03","3":"2021-07-03","4":"2021-07-03","5":"2021-07- 
               03","6":"2021-07-03","7":"2021-07-03"},
"guessed entry date":{"1":"2021-07-03","2":"2021-07-03","3":"2021-07-03","4":"2021-07- 
                       03","5":"2021-07-03","6":"2021-07-03","7":"2021-07-03"},
}

This is what I’ve written in my main.js file and I think there is an error with how I have defined my columns. Any clue to what the error might be?

    $(document).ready( function () {
    $('#example').DataTable({
        'ajax': './desired_forms/mt_in_json_form.json'
        'columns': [
          {"status"},
          {"funds code"},
          {"amount"},
          {"id"},
          {"customer reference"},
          {"bank reference"},
          {"extra details"},
          {"currency"},
          {"date"},
          {"entry date"},
          {"guessed entry date"}
        ]
    });
} );
