IXlTableColumnCollection Interface

A collection of columns in a table.

Namespace: DevExpress.Export.Xl

Assembly: DevExpress.Printing.v24.1.Core.dll

NuGet Package: DevExpress.Printing.Core

Declaration

public interface IXlTableColumnCollection :
    IXlReadonlyCollection<IXlTableColumn>,
    IEnumerable<IXlTableColumn>,
    IEnumerable

The following members return IXlTableColumnCollection objects:

Remarks

The IXlTableColumnCollection collection contains the IXlTableColumn objects and is populated automatically when you start generating a table by calling the IXlRow.BeginTable method.

To access a collection of table columns, use the IXlTable.Columns property. An individual table column represented by an IXlTableColumn object can be accessed by its name or zero-based index in the IXlTableColumnCollection collection.

Example

Note

A complete sample project is available at https://github.com/DevExpress-Examples/excel-export-api-examples

IXlTable table;
// Specify an array containing column headings for a table.
string[] columnNames = new string[] { "Product", "Category", "Amount" };

// Create the first row in the worksheet from which the table starts.
using (IXlRow row = sheet.CreateRow())
{
    // Start generating the table with a header row displayed.
    table = row.BeginTable(columnNames, true);
    // Specify the total row label.
    table.Columns[0].TotalRowLabel = "Total";
    // Specify the function to calculate the total.
    table.Columns[2].TotalRowFunction = XlTotalRowFunction.Sum;
    // Specify the number format for the "Amount" column and its total cell.
    XlNumberFormat accounting = @"_([$$-409]* #,##0.00_);_([$$-409]* \(#,##0.00\);_([$$-409]* ""-""??_);_(@_)";
    table.Columns[2].DataFormatting = accounting;
    table.Columns[2].TotalRowFormatting = accounting;
}

// Generate table rows and populate them with data.
using (IXlRow row = sheet.CreateRow())
    row.BulkCells(new object[] { "Camembert Pierrot", "Dairy Products", 17000 }, null);
using (IXlRow row = sheet.CreateRow())
    row.BulkCells(new object[] { "Gnocchi di nonna Alice", "Grains/Cereals", 15500 }, null);
using (IXlRow row = sheet.CreateRow())
    row.BulkCells(new object[] { "Mascarpone Fabioli", "Dairy Products", 15000 }, null);
using (IXlRow row = sheet.CreateRow())
    row.BulkCells(new object[] { "Ravioli Angelo", "Grains/Cereals", 12500 }, null);

// Create the total row and finish the table.
using (IXlRow row = sheet.CreateRow())
    row.EndTable(table, true);
