How can I put a line and space in the PDF header?

otavio_laskosk_pc

I put this header and I don't manage add a line and space to separate from grid.

source:

    var tabExp = $('#tabelaDataTableExport').DataTable({
        //dom: '<Bf<t>ip>',

        dom: "<'row'<'col-sm-6'B><'col-sm-6'f>>" + "<'row'<'col-sm-12'tr>>" + "<'row'<'col-sm-6'i><'col-sm-6'p>>",
        buttons: [ 

            {
                
                customize: function ( doc ) {

  doc['header']=(function(page, pages) {
                        return {
                            columns: [
                                
                            {
                                alignment: 'left',
                        image: 'logo.jpg',
                        width: 100
                        
                                /*text: [
                                    { text: page.toString(), italics: true },
                                    ' / ',
                                    { text: pages.toString(), italics: true }
                                ]*/
                            },
                            {
                                bold: true,
                                fontsize:'100px',
                                text:'Rlatório de Previsões',
                                alignment: 'center',
                                margin:[80,10,0,]
                                
                            },
                            {
                                
                                text: [
                                    { text: page.toString(), italics: true },
                                    ' / ',
                                    { text: pages.toString(), italics: true }
                                ],
                                
                                alignment: 'right',
                                margin:[100,10,0]
                            }

                            
                            
                            ],
                            alignment: 'center',
                            margin: [60, 18,80,100]


                           
                        };
                    });
                    
                    
              },
            }
        ],

        language: {
            url: uri_arquivo
        }

        //order: [[ 0, "asc" ]]
    });

Anyone know how do it?

And finally if you go the pdfmake site, on the margin page it shows how to add a margin to the header (this will push down the table data as you want).

Hi Colin,

Thank you by your reply.

According the tutorial you've passed, It works by a text and style. I can't apply it in the funtion doc['header'] in the customize: function ( doc ).

doc['header'] in the customize: function ( doc ).

Why not? The customize callback is just a callback function that will let you modify the pdfmake document description that the pdf button creates. All formatting is done by pdfmake itself, so if you want to customise the output, you'd need to modify the document structure.

Hi Allan,

Thank you by your reply.

I've tried to add the command margin: [0, 0,0,80] in the function margin: [60, 18,80,100,80] according the tutorial but it hasn't worked.

Follow the source I'm using.

I couldn't get the margin to work with the title, no idea why, since it should be fine. However, you can fudge it like the example here

Cheers,
