Examples

public string[][] datastring = new string[3][];
// Specify values for the table
datastring[0] = new string[] { "111", "Maxim", "100" };
datastring[1] = new string[] { "222", "Calvin", "95" };

// Create a new document
PdfDocument document = new PdfDocument();
//Create a Page
PdfPage page = document.Pages.Add();
//Create the PdfLightTable
PdfLightTable pdfLightTable = new PdfLightTable();
// Setting the DataSourceType as Direct
pdfLightTable.DataSourceType = PdfLightTableDataSourceType.External;
//Subscribing Events
pdfLightTable.QueryRowCount += new QueryRowCountEventHandler(table_QueryRowCount);
pdfLightTable.QueryColumnCount += new QueryColumnCountEventHandler(table_QueryColumnCount);
pdfLightTable.QueryNextRow += new QueryNextRowEventHandler(table_QueryNextRow);
//Draw PdfLightTable.
pdfLightTable.Draw(page, new PointF(0, 0));
//Save the document.
document.Save("Output.pdf");
//Close the document
document.Close(true);
