How to split large data table into multiple pages

[DktPhl2019]

Hello

I am using flutter pdf on Windows 11.

Describe the bug
Table data with more than 10 records shows blank pdf.
I need to split large table data into multiple pages.

To Reproduce - Please see code below:

mappedList = (list1.isNotEmpty && list2.isNotEmpty && list2.isNotEmpty && list4.isNotEmpty) ? [
        for (int i = 0; i < list1.length; i++)
          myData(list1[i],list2[i],list3[i],list4[i])
      ] : [];
	  
	final pdf = pw.Document();
      pdf.addPage(pw.Page(pageFormat: PdfPageFormat.standard,build: (pw.Context context) {
            return pw.Column(children: [
                pw.Table(border: pw.TableBorder.all(),children: [
                    pw.TableRow(children: [
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Name',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Salary',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Department',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Location',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                      ],
                    ),
                  ...mappedList.map((item) => pw.TableRow(children: [
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text(item.Name)),
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text(item.Salary)),
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text(item.Department)),
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text(item.Location))),
                  ])),
                  ],
                ),
                pw.Spacer(), // Dynamic spacing to move content up
                pw.Align(alignment: pw.Alignment.bottomCenter,child: pw.Text('Page 1',style: pw.TextStyle(fontSize: 9, color: PdfColors.grey))),
              ],
            );
          },
        ),
      );
      final file = File('${myPath}/my_file.pdf');
      file.writeAsBytes(await pdf.save());//  
	  

Expected behavior
I should see table split into multiple pages.

Try and use pw.MultiPage instead of pw.Page

[leocirto]

Table can span across multiple pages.
Just remove the Column and change Page to MultiPage.

For example:

  Future<Uint8List> _builPdfPreview(final PdfPageFormat format) async {
     final pdf = pw.Document();
      pdf.addPage(
        pw.MultiPage(  // pw.Page(
            pageFormat: format,
            build: (final pw.Context context) {
            return [ // pw.Column( children: [
                pw.Table( border: pw.TableBorder.all(),
                 children: [
                  pw.TableRow(children: [
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Name',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Salary',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Department',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                        pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('Location',style: pw.TextStyle(fontSize: 9, fontWeight: pw.FontWeight.bold))),
                  ] ),

                 for( int k = 0; k < 20; k++ )
                  pw.TableRow( children: [
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('row $k')),
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('row $k')),
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('row $k')),
                    pw.Padding(padding: const pw.EdgeInsets.all(8),child: pw.Text('row $k')) 
                  ] ),
                 ] ),
                pw.Spacer(), // Dynamic spacing to move content up
                pw.Align(alignment: pw.Alignment.bottomCenter,child: pw.Text('Page 1',style: const pw.TextStyle(fontSize: 9, color: PdfColors.grey))),
              // ] )
            ];
          },
        ),
      );
     return pdf.save();
  }

Output:
