Generating PDF from complex html table using JSPDF

Question

I am trying to generate pdf from html using JSPDF and html having one complex table, Added image below.

You can see in this Fiddle, What i tried so far.

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('Test.pdf');
}, margins);

Problem is, when i try to generate pdf i am getting

Uncaught TypeError: Cannot read property 'name' of undefined

Is it possible to use JSPDF for this kind of complex table or will it only work for a simple table.

EDIT: Solved this by different way, This is what i did

1. I converted HTML Table into Canvas html2canvas.js
2. You can get canvas as Base64 image using canvas.toDataURL("image/jpeg")
3. Once i got Base64 image, Created empty PDF using JSPDF and using addImage feature of JSPDF, i manage to embed Base64 image inside PDF.

If you need charts and images as part of PDF -> charts and images as part of PDF

Credit goes to my brain.

Answer 1

I was able to fix this by modifying line 6203 of jspdf.debug.js (on version 1.2.61) to this:

while (j < tableRow.cells.length && headers[j] != undefined) {

Which was originally:

while (j < tableRow.cells.length) {

Alternatively, I could make it go away by adding another td to the tr it was processing (it only had one td, which apparently caused the problem).

I'm thinking I'll try to submit it as a bug fix.

Answer 2

1. Checkout the pdfmake Playground (It is supposed to work in the browser and is MIT-licensed.)
2. Select TABLES in the top menu of the Playground.
3. Scroll down the example pdf, there is a section illustrating Colspan-capabilities.

Answer 3

I stepped through the code using the chrome debugger, and it looks like jspdf is is having an issue with colspan in the first row of the table.

It seems like a bug in their library, where you can't use col span in the header or first row of each table.

Answer 4

Remove All the colspan Attribute And Rowspan Attribute From td Tag And Apply blank td then try.
