  Unfortunately the last column's Datatables config is cutoff in your screenshot. Looks like you have columns.defaultContent set to display the buttons. But if the last column has data then that suggests you have used columns.data to define the row object to display. columns.defaultContent will be displayed only if the columns.data is not found in the row. You might need to set columns.data to null in that column, like this:

  data: null,
  

  If you still need help then please copy and paste the Datatables init code so we can see everything you have.

  Do you have some code that updates the table? You have columns.defaultContent in the first column so the column should show empty strings. But the column looks like it has an index that is added. I wonder if you have some other code updating the last column.

  Please post a link to your page or a test case replicating the issue so we can help debug.
