jquery - DataTables Export PDF with 100% Width

Question

I am attempting to export my tables to PDF with a 100% width. I have tried the following but I have been unsuccessful

var settings={};
settings.buttons = [
    {
        extend:'pdfHtml5',
        text:'Export PDF',
        orientation:'landscape',
        customize : function(doc){ 
            doc.styles['table'] = { width:100% }
        }
    }
];
$('.dTable').dataTable(settings);

Answer 1

Found an easier and quicker way to do it.

{
  extend: 'pdf',
  customize: function (doc) {
    doc.content[1].table.widths = 
        Array(doc.content[1].table.body[0].length + 1).join('*').split('');
  }
}

What happens here is as so:

doc.content[1].table.widths is an array of widths for each column, and if each of them is a '*' it means that the table will fit 100% of the page with the columns distributed evenly.

Array(doc.content[1].table.body[0].length + 1) creates an array in the length of all the columns of my table.

.join('*') creates a string from all the cells in the array with a '*' for each.

.split(''); splits it back into an array.

Hope I helped someone along the way.
