Add dpownload functionality

[gauravmak]

I think you are mixing 2 things here. Downloading a file is a separate task and Laratables needs to just return the file name which is already in the column coaname.

If you want to return a download button instead of just the file name, you can use the (Customize the column value)[https://github.com/freshbitsweb/laratables#customizing-column-values] and return button HTML instead. Something like this:

/**
 * Returns truncated name for the datatables.
 *
 * @return string
 */
public function laratablesCoaName()
{
    return view('buttom_html', ['coa_name' => $this->coa_name])->render();
}

And buttom_html blade view file can contain buttom HTML.
