Datatable - link colum cell

I'm using Datatable to display data and charge a table using an AJAX call to a file stored in a JSON object.

I need that one of columns be a text with a link that opens a modal window.

    "columns": [
        { 'data': 'BATCH'},
        { 'data': 'DATE'},
        { 'data': 'STARTTIME'},
        { 'data': 'FINISHTIME'},
        { 'data': 'STATUS'},
    ]

For example, colum Batch is loaded from JSON file, and I want to be a link that opens a modal window.

Please, where do I write the link, in the JSON, when to load the DataTable, or with the API DataTable?

Thank you.

Regards,
