Examples
// Create a new document
PdfDocument document = new PdfDocument();
//Create a Page
PdfPage page = document.Pages.Add();
//Create DataTable for source
DataTable dataTable = new DataTable("myTable");
dataTable.Columns.Add("ID1");
dataTable.Columns[0].Caption = "id";
dataTable.Columns.Add("ID2");
object[] values = new object[] { "Roll Number", "Student Name" };
dataTable.Rows.Add(values);
values = new object[] { "011", "Cris" };
dataTable.Rows.Add(values);
values = new object[] { "011", "Clay" };
dataTable.Rows.Add(values);
//Create the PdfLightTable
PdfLightTable pdfLightTable = new PdfLightTable();
// Subscribe the begin row event
pdfLightTable.BeginRowLayout += new BeginRowLayoutEventHandler(table_BeginRowLayout);
//Set the data source
pdfLightTable.DataSource = dataTable;
//Draw PdfLightTable.
pdfLightTable.Draw(page, new PointF(0, 0));
//Save the document.
document.Save("Output.pdf");
//Close the document
document.Close(true);
