I am following this guide in order to add multiple data in my DataTables (js plugin) column:

https://datatables.net/forums/discussion/58795/add-multiple-value-in-column

Here is the specific column in question:

{ data: 'shift_name', name: 'shift_name', width: '15%', 
    "render": function ( data, type, row, meta )
    {
        return row.shift_name ? row.shift_name : 'N/A';
    },
    createdCell: function (td, cellData, rowData, row, col) {
        return $(td).css({
            'font-weight': "700"
        });
    }
},

The Output:

Now I am trying to add another data underneath shift_name so here is what I tried first:

return row.shift_name ? row.shift_name : 'N/A' + '<br>hello';

The code above does not show the "hello" in each row

I also Tried adding a + at the start:

return + row.shift_name ? row.shift_name : 'N/A' + '<br>hello';

but for some reason my shift_name data does not get read this way:

What is the correct way in adding multiple data in a row in my situation?

You are using the JavaScript conditional operator ? :.

Your logic basically means "if row.shift_name has a value, then display that value (and nothing else!) - but otherwise display N/A plus some additional text".

So, your logic means you only display that additional text if row.shift_name does not contain any value.

You can use parentheses to fix this:

return (row.shift_name ? row.shift_name : 'N/A') + '<br>hello';

Now, the conditional ? : operator is evaluated first - and then the extra text is appended to whatever the result of that operator is.

See also Understanding JavaScript Truthy and Falsy for a more precise description of how the condition is evaluated in your conditional operator.
