Datatables.net: Set column width when exporting to XLSX - excel

Question

i have datatables table and i want export content of this table.
Because some headers are so long, i must set specific text of headers. All works fine, but columns with customized text are still so long.
customize: function( xlsx ) {
var sheet = xlsx.xl.worksheets['sheet1.xml'];
// Exported excel custom properties
$('row:first c', sheet).attr( 's', '7' );
$('c[r=B1] t', sheet).text( 'Date' ).;
$('c[r=C1] t', sheet).text( 'Type' );
$('c[r=E1] t', sheet).text( 'Subject' );
}
}]
Pls, is possibe set specific width for columns with "new" - shorter texts?
Thanks for any answers.

Answer 1

"customize": function (xlsx) {
var sheet = xlsx.xl.worksheets['sheet1.xml'];
$('row:first c', sheet).attr( 's', '2' );
$('row:first c is t', sheet).each(function () {
if (this.innerHTML == 'creationdate') { this.innerHTML = 'Date' }
if (this.innerHTML == 'ty') { this.innerHTML = 'Type' }
if (this.innerHTML == 'sub') { this.innerHTML = 'Subject' }
});
}

Answer 2

Use the customize tag inside the excel button to configure the width options
{
title: "",
exportOptions: { ... }
customize: function (xlsx: any) {
var sheet = xlsx.xl.worksheets["sheet1.xml"];
var col = $("col", sheet);
var col = $('col', sheet);
col.each(function () { //update all columns with width 30
$(this).attr('width', 30);
});
$(col[0]).attr("width", 7); // update specific columns
$(col[4]).attr("width", 7); // update specific columns
}
}
