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);

```
