Table.Range Property

Gets or sets the range of cells that contains the table.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v19.2.Core.dll

Declaration

CellRange Range { get; set; }
Property Range As CellRange
CellRange Range { get; set; }
Property Range As CellRange
CellRange Range { get; set; }
Property Range As CellRange

Property Value

Type Description
CellRange

A CellRange object specifying the cell range that contains the entire table.

Property Value

Type Description
CellRange

A CellRange object specifying the cell range that contains the entire table.

Property Value

Type Description
CellRange

A CellRange object specifying the cell range that contains the entire table.

Remarks

The cell range that the Range property returns for a sample table is highlighted in the image below.

SpreadsheetControl_Table_Range

To get the cell range that contains table data only (excluding the header and total rows), use the Table.DataRange property. The Table.HeaderRowRange and Table.TotalRowRange properties return cell ranges containing a table's header row and total row respectively.

To obtain a cell range of an individual table column, use TableColumn.Range or TableColumn.DataRange.

Examples

This example demonstrates how to create a table from a range of cells. The sample range includes a list of products and invoice information on each product: price, quantity and discount.

SpreadsheetControl_ImportDataTable

The resulting table will provide an additional column to calculate the amount per product, and an additional row to show the total amount. Follow the steps below:

  1. Create a Table

    Add a new Table object to the worksheet's collection of tables (Worksheet.Tables) via the TableCollection.Add method. Pass the following parameters:

    • The range of cells that you wish to format as a table. Use the "B2:F5" range reference instead of "B2:E5" to include an additional column to the right that calculates and displays product amounts.
    • A Boolean value indicating that the top row of the specified range will be the table header.
  2. Format the Table

    Format the table by applying one of the built-in table styles. To do this, set the Table.Style property to the table style object from the IWorkbook.TableStyles collection. Access the desired style by its BuiltInTableStyleId identifier.

  3. Table Columns

    Access table columns by their indexes from the column collection that the Table.Columns property returns.

  4. Table Header Row

    To specify the last column header, set its TableColumn.Name property to "Amount". Headers of other table columns are automatically set to the values of the corresponding cells:

    • table.Columns[0].Name = "Product"
    • table.Columns[1].Name = "Price"
    • table.Columns[2].Name = "Quantity"
    • table.Columns[3].Name = "Discount"
  5. Calculated Column

    Specify the formula to calculate the product amount, and assign it to the Amount column using the TableColumn.Formula property. In the formula, refer to table columns by their headers.

  6. Table Total Row

    Set the Table.ShowTotals property to true, to display the total row at the bottom of the table.

  7. Total Row Function

    Specify the function to calculate the total amount. To do this, set the TableColumn.TotalRowFunction property of the Amount column to TotalRowFunction.Sum.

    Note

    In the total row, you can use any formulas you wish, not only functions listed by the TotalRowFunction enumerator. To use a custom formula in the total row, assign it to the TableColumn.TotalRowFormula property of the required table column.

  8. Table Ranges and Data Ranges

    Specify number formats to display numbers as currency values in the Price and Amount columns, and as percentage values in the Discount column. To access the data range of a table column, use the TableColumn.DataRange property.

    Use the Table.HeaderRowRange and Table.TotalRowRange properties to access table header and total row ranges, and set the alignment.

    Change the width of table columns. To do this, access the table range via the Table.Range property, and use its CellRange.ColumnWidthInCharacters property.

' Insert a table in the worksheet.
Dim table As Table = worksheet.Tables.Add(worksheet("B2:F5"), True)

' Format the table by applying a built-in table style.
table.Style = workbook.TableStyles(BuiltInTableStyleId.TableStyleMedium27)

' Access table columns and name them.
Dim productColumn As TableColumn = table.Columns(0)
productColumn.Name = "Product"
Dim priceColumn As TableColumn = table.Columns(1)
priceColumn.Name = "Price"
Dim quantityColumn As TableColumn = table.Columns(2)
quantityColumn.Name = "Quantity"
Dim discountColumn As TableColumn = table.Columns(3)
discountColumn.Name = "Discount"
Dim amountColumn As TableColumn = table.Columns(4)
amountColumn.Name = "Amount"

' Set the formula to calculate the amount per product 
' and display results in the "Amount" column.
amountColumn.Formula = "=[Price]*[Quantity]*(1-[Discount])"

' Display the total row in the table.
table.ShowTotals = True

' Set the label and function to display the sum of the "Amount" column.
discountColumn.TotalRowLabel = "Total:"
amountColumn.TotalRowFunction = TotalRowFunction.Sum

' Specify the number format for each column.
priceColumn.DataRange.NumberFormat = "$#,##0.00"
discountColumn.DataRange.NumberFormat = "0.0%"
amountColumn.Range.NumberFormat = "$#,##0.00;$#,##0.00;"""";@"

' Specify horizontal alignment for header and total rows of the table.
table.HeaderRowRange.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Center
table.TotalRowRange.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Center

' Specify horizontal alignment to display data in all columns except the first one.
For i As Integer = 1 To table.Columns.Count - 1
    table.Columns(i).DataRange.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Center
Next i

' Set the width of table columns.
table.Range.ColumnWidthInCharacters = 10
