Can I force a combination of some non-visible columns + visible columns into the export file ?
Can I force a combination of some non-visible columns + visible columns into the export file ?
Hi!
I am trying to make a collection of export options on my table and was wondering if there was a way for my "Export Visible Columns Only " for me to include a few of my non-visible columns that have a class on them of ".always-export"? There are some standard fields that they don't see in the table that I want to make sure are included in combination with the visible columns.
{
extend: 'collection',
"text": '<i class="far fa-file-excel mr-3 ml-3"></i>',
className: 'btn-data-table btn-sm m-b-xs d-print-none data-table-icon-btn d-none d-sm-block',
buttons: [
{
extend: 'excelHtml5',
"text": '<i class="far fa-file-excel mr-2"></i>Export Visible Columns Only (* not included)',
"title":'',
titleAttr: 'Use the Column Selectors to select the columns to include in your export. Constituent First Name and Last will always be included. Columns with a * contain combined data and are not exportable. All other columns must be selected using the Column Selector before export..',
"filename": '{{export_file_name}}',
"exportOptions": {
columns: ':visible', // want to also include the class of .always-export (which is different then the visible columns)
"modified": {
filter:true
}
}
}
],
attr: {
id: 'ExportButtonCollection'
}
}

Yep, the
exportOptions.columnsiscolumn-selector, which can be a function - so in there you can return both visible and with the class.Colin
@colin would it be something like this?
"exportOptions": {columns: function () {var columns = table.columns( [0,1,2,':visible:not(.never)'] );return columns},No, the function needs to return true or false - it gets called for each of the columns. This is the example from the reference page I linked to in my last reply,
