Render table from the data source

Aspose.PDF allows you to create the table with DataSource from DataSet, Data Table, arrays and IEnumerable objects using PdfLightTable class

The Table class is used to process tables. This class gives us the ability to create tables and place them in the document, using Rows and Cells. So, to create the table, you need to add the required number of rows and fill them with the appropriate number of cells.

The following example creates the table 4x10.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddTable()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Add page
        var page = document.Pages.Add();

        var table = new Aspose.Pdf.Table
        {
            // Set column auto widths of the table
            ColumnWidths = "25% 25% 25% 25%",

            // Set cell padding
            DefaultCellPadding = new Aspose.Pdf.MarginInfo(10, 5, 10, 5), // Left Bottom Right Top

            // Set the table border color as Green
            Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, .5f, Aspose.Pdf.Color.Green),

            // Set the border for table cells as Black
            DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, .2f, Aspose.Pdf.Color.Green),
        };

        for (var rowCount = 0; rowCount < 10; rowCount++)
        {
            // Add row to table
            var row = table.Rows.Add();

            // Add table cells
            for (int i = 0; i < 4; i++)
            {
                row.Cells.Add($"Cell ({i + 1}, {rowCount + 1})");
            }
        }

        // Add table object to first page of input document
        page.Paragraphs.Add(table);

        // Save PDF document
        document.Save(dataDir + "AddTable_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddTable()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    // Create PDF document
    using var document = new Aspose.Pdf.Document();

    // Add page
    var page = document.Pages.Add();

    var table = new Aspose.Pdf.Table
    {
        // Set column auto widths of the table
        ColumnWidths = "25% 25% 25% 25%",

        // Set cell padding
        DefaultCellPadding = new Aspose.Pdf.MarginInfo(10, 5, 10, 5), // Left Bottom Right Top

        // Set the table border color as Green
        Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, .5f, Aspose.Pdf.Color.Green),

        // Set the border for table cells as Black
        DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, .2f, Aspose.Pdf.Color.Green),
    };

    for (var rowCount = 0; rowCount < 10; rowCount++)
    {
        // Add row to table
        var row = table.Rows.Add();

        // Add table cells
        for (int i = 0; i < 4; i++)
        {
            row.Cells.Add($"Cell ({i + 1}, {rowCount + 1})");
        }
    }

    // Add table object to first page of input document
    page.Paragraphs.Add(table);

    // Save PDF document
    document.Save(dataDir + "AddTable_out.pdf");
}

When initializing the Table object, the minimal skin settings were used:

ColumnWidths - width of columns (by default).
DefaultCellPadding - the default fields for the table cell.
Border - table frame attributes (style, thickness, color).
DefaultCellBorder - attributes of the cell frame (style, thickness, color).

Exporting data from an array of objects

The Table class provides methods for interacting with ADO.NET data sources - ImportDataTable and ImportDataView. The first method imports data from the DataTable, the second from the DataView. Premising that these objects are not very convenient for working in the MVC template, we will limit ourselves to a brief example. In this example (line 50), the ImportDataTable method is called and receives as parameters a DataTable instance and additional settings like the header flag and the initial position (rows/cols) for the data output.
