Data Table customising pdf

Question

I am using jQuery Data Table to export table as pdf.Now the pdf all the text are left aligned.How can I change it to right aligned?I need to add custom css to the exported pdf.

Here is my code

$('#reporTable').DataTable({

    "paging" : false,
    "ordering": false,
    "info" : false,
    "searching" : false,

    dom: 'T<"clear">lfrtip',
    tableTools: {
    "sSwfPath": "/javascripts/js/dataTables/tools/swf/copy_csv_xls_pdf.swf",

    "aButtons": [
    {
    "sExtends": "pdf",
    "sTitle": filename,
    "sPdfOrientation": "landscape",
    "sPdfMessage": out_name+":" + msg
    },

    ],

    }

    });

Answer 1

Use the customize callback. It is not so well documented, see this answer for some references, or you could simply try to investigate the passed doc literal yourself. Basically

customize: function(doc) {
  doc.defaultStyle.alignment = 'right';
  doc.styles.tableHeader.alignment = 'right';
}

will end up in a PDF with right aligned headers and cell content. A sample could be

$('#example').DataTable( {
  dom: 'Bfrtip',
  buttons: [{
   extend: 'pdfHtml5',
   customize: function(doc) {
     doc.defaultStyle.alignment = 'right';
     doc.styles.tableHeader.alignment = 'right';
   }  
 }]
})
