Datatable not rendering.

Roger Jarrett

Hi I have some data that does not render in Datatable. Data with less coloumns renders ok. A zip file containing the failing html is attached. I have sent a datatable debugger output which is uxufaj.

Any suggestions as to how to fix it would be appreciated.

You are getting this error:

Uncaught TypeError: Cannot read property 'mData' of undefined

Looks like you have 29 columns but have only defined 28 with columns:

            columns: [
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false },
                { orderable: false }
            ]

You need to add one more column definition. You can use null if you don't want to define anything for one of the columns. Or you can replace your columns with a more simpler columnDefs, something like this:

            columnDefs: [
              { targets: '_all',
                orderable: false
              },
            ]
