This method provides the ability to retrieve the names of selected columns that has been set through the columns.name option. This can be useful for the identification of columns, particularly when using orthogonal data, however, setting a column name does not functionally change the behaviour of a DataTable.

I'm trying to get my column names: table.columns().names() My DataTable does have names: columns: [ { name: "abc", ...}, { name: "def", ...} ] However I get the following error: .columns(...).names is not a function Am I missing something obvious?

Yeah - ideally don't use information from the settings object. It is considered to be private. it can, may and does change between versions at times, so use with caution. If you do use it, wrap any use into a plug-in API method so if it does break in future, you can update it in just one place. Allan

You could use this little plug-in: $.fn.dataTable.Api.register( 'columns().names()', function () { return this.iterator( 'column', function ( settings, column ) { return settings.aoColumns[column].sName; }, 1 ); } ); And call like: table.columns().names(). I'm assuming you are referring to a name as in columns.name? Allan

Hi @colin Just have a search to columns().names() here and click on column().name() or in case columns().name() to get the link B)

I haven't tested it, but this should do it: $.fn.dataTable.Api.registerPlural( 'columns().names()', 'column().name()', function ( setter ) { return this.iterator( 'column', function ( settings, column ) { var col = settings.aoColumns[column]; if ( setter !== undefined ) { col.sName = setter; return this; } else { return col.sName; } }, 1 ); } );

Very clever - nice one :smile:. Thanks for sharing your solution with us. I'm going to add a columns().names() method in future, the current absence of which is what I was referring to above. Allan

Hello @allan I see the documentation of column().name() or columns().names() and make some tests, but they are undefined. This function has depreciated or removed?

var count = 1; var columnsNames = []; $('thead th').each(function() { columnsNames.push({'data': $(this).data('name')}); }); var table = $('.myDataTable').DataTable({

I have defined the columns.names and I can use
