Render tabel dari sumber data

Aspose.PDF memungkinkan Anda untuk membuat tabel dengan DataSource dari DataSet, Data Table, array, dan objek IEnumerable menggunakan kelas PdfLightTable.

Kelas Table digunakan untuk memproses tabel. Kelas ini memberi kita kemampuan untuk membuat tabel dan menempatkannya dalam dokumen, menggunakan Rows dan Cells. Jadi, untuk membuat tabel, Anda perlu menambahkan jumlah baris yang diperlukan dan mengisinya dengan jumlah sel yang sesuai.

Contoh berikut membuat tabel 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");
}

Saat menginisialisasi objek Table, pengaturan skin minimal digunakan:

• ColumnWidths - lebar kolom (secara default).
• DefaultCellPadding - bidang default untuk sel tabel.
• Border - atribut bingkai tabel (gaya, ketebalan, warna).
• DefaultCellBorder - atribut bingkai sel (gaya, ketebalan, warna).

Mengekspor data dari array objek

Kelas Table menyediakan metode untuk berinteraksi dengan sumber data ADO.NET - ImportDataTable dan ImportDataView. Metode pertama mengimpor data dari DataTable, yang kedua dari DataView. Dengan asumsi bahwa objek-objek ini tidak terlalu nyaman untuk bekerja dalam template MVC, kita akan membatasi diri pada contoh singkat. Dalam contoh ini (baris 50), metode ImportDataTable dipanggil dan menerima sebagai parameter sebuah instance DataTable dan pengaturan tambahan seperti flag header dan posisi awal (baris/kolom) untuk output data.
