I must to generate a table and export it to html. I initially tried do this use php and phpexcel but my client server is to slow (some times my table has 2500rows). Now I'm try get table via jquery/ajax and install js plugin to export. I am currently using datatables and my code view like this:

<!DOCTYPE html>

It might be a late answer however I'm gonna lead you to a solution.

First in order to change the orientation of PDF from Portrait to Landscape assuming your using pdfHtml5 you need to define the orientation as following orientation: 'landscape', this will help you export the PDF file in landscape.

Exporting images with PDF requires a customization and to encode your image you can't export the images as a normal HTML tag you shall at first encode it as base64 encoder 

$image = 'http://localhost/img.jpg';

 // Read image path, convert to base64 encoding
 $type = pathinfo($image, PATHINFO_EXTENSION);
 $data = file_get_contents($image);

 $imgData = base64_encode($data);

 // Format the image SRC:  data:{mime};base64,{data};
 $src = 'data:image/' . $type . ';base64,'.$imgData;

After encoding the images you need to customize your PDF export as following

        {
            extend: 'pdfHtml5',
            orientation: 'landscape',
            customize: function (doc) {
               if (doc) {
                    for (var i = 1; i < doc.content[1].table.body.length; i++) {
                        doc.content[1].table.body[i][1] = {
                            image: '<?php echo $src; ?>,
                        };
                    }
                }
            },
            exportOptions: {
                stripHtml: false
        }
        }

This should do the trick.

extend: 'pdfHtml5',
      customize: function(doc) {
       //find paths of all images, already in base64 format
       var arr2 = $('.img-fluid').map(function(){
                                return this.src;
                 }).get();
                 
             
 
     for (var i = 0, c = 1; i < arr2.length; i++, c++) {
                       doc.content[1].table.body[c][6] = {
                         image: arr2[i],
                         width: 100
