Nested/Sub Tables with PDFMake

Question

How do I use nested/sub tables with PDFmake? I've tried simply putting in multiple tables but that doesn't automatically repeat the top level table's header for page breaks.

Answer 1

This code is a simplified example of using a sub-table. It is adapted from tables section of the pdfmake playground (wasn't easy to find via Google searching).

Paste the following into: http://pdfmake.org/playground.html

// playground requires you to assign document definition to a variable called dd

var dd = {
    content: [

                { text: 'A simple table with nested elements', style: 'subheader' },
                'It is of course possible to nest any other type of nodes available in pdfmake inside table cells',
                {
                        style: 'tableExample',
                        table: {
                                headerRows: 1,
                                body: [
                                        ['Column 1', 'Column 2'],
                                        [
                                                {
                                                        stack: [
                                                                'Let\'s try an unordered list',
                                                                {
                                                                        ul: [
                                                                                'item 1',
                                                                                'item 2'
                                                                        ]
                                                                }
                                                        ]

                                                [
                                                    'or a nested table',
                                                    {
                                                        table: {
                                                            body: [
                                                                [ 'Col1', 'Col2', 'Col3'],
                                                                [ '1', '2', '3'],
