Try using the jQuery :empty selector: columns: ':not(:empty)' Allan

Do you mean you want to set the data for those columns to be null? If so, that's an edit action and you could use the edit() method in a custom button to do that. Allan

Figured it out. Had columns in the wrong block. It should be: buttons: [ { extend: 'csvHtml5', text: 'csv visible rows', filename: 'OASISHistoryExport_'+moment().format('YYYY-MM-DD_HH-mm-ss'), exportOptions: { modifier: { search: 'none' }, //columns: [2,3,4,5,6,7,8,9,10,11,13,14,15,16,17,18,20,21,22,23,25,26,27,28,29,30,31,32,33,36,37] columns: '.exp' } } ]

to each of the columns (1, 2, & 8)

match the number of columns in the table. So
