DataTable export to csv support

[gatapia]

It would be great to have a 'toCsv' method on the table. This would export headers and table contents to a csv file. I currently hacked this using jQuery but it should be contained within the table itself I think.

So this would work as follows:

# template
<p-datatable #table>...</p-datatable>
<button (click)="tocsv(table.toCsv())">Export to CSV</button>

# component
tocsv(csv: string) {
  // Server needs to "download" csv file to browser for IE9 support
  http.post('tocsv', {data: csv});
}

I send the csv to the server so the server creates a temporary file to send the the browser. However, it appears that this may be possible in pure JS: stack overflow

This would be even better (as long as IE9 is supported).

Great idea, we'll check this. Thanks. In PrimeFaces, we can export to pdf, csv, xml and excel so PrimeNG should have some sort of export as well.
