jspdf first PDF page is blank - jspdf

Question

Im trying to get my jspdf to not save a blank page PDF. I been trying many examples, but nothing works :(. My table content is saved correct, with a image on the second page of the PDF, but my first page is blank.
var pdf = new jsPDF('o', 'pt', 'a6');
//pdf.autoTable(this.columns, this.data);
//var width = pdf.internal.pageSize.width;
//var height = pdf.internal.pageSize.height;
pdf.addPage('1800','900');
pdf.addImage(imgData, 'PNG', 120, 40, 120, 100);
pdf.setTextColor(0,0,0);
pdf.text(120, 20, 'BOOKINGS');
pdf.setFontSize(22);
// 'o', 'pt', 'a4'
// 'p', 'pt', 'letter'
// source can be HTML-formatted string, or a reference
// to an actual DOM element from which the text will be scraped.
source = jQuery('.dataTables_wrapper')[0];
// we support special element handlers. Register them with jQuery-style
// ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
// There is no support for any other type of selectors
// (class, of compound) at this time.
specialElementHandlers = {
// element with id of "bypass" - jQuery style selector
'#bypassme': function (element, renderer) {
// true = "handled elsewhere, bypass text extraction"
return true
}
};
margins = {
top: 120,
bottom: 0,
left: 0,
width: 2000
};
// all coords and widths are in jsPDF instance's declared units
// 'inches' in this case
pdf.fromHTML(
source, // HTML string or DOM elem ref.
margins.left, // x coord
margins.top, { // y coord
'width': margins.width, // max width of content on PDF
'elementHandlers': specialElementHandlers
},
function (dispose) {
// dispose: object with X, Y of the last line add to the PDF
// this allow the insertion of new lines after html
pdf.save('bookings.pdf');
}, margins);
}

The first page is blank because adding a page is the first call you make after calling the jsPDF constructor. The constructor does already create a (first) blank page. To get rid of the additional empty page at the start of the document, either delete the first page calling doc.deletePage(1), or do not add a page after the constructor is being called.
