Gets or sets the name of the table column.
Namespace : DevExpress.Spreadsheet
Assembly : DevExpress.Spreadsheet.v25.2.Core.dll
NuGet Package : DevExpress.Spreadsheet.Core
string Name { get; set; }
Property Name As String
| Type | Description |
|---|---|
| String |
A String value that specifies the table column name.
|
Table names and table column names can be used in formulas to refer to the corresponding table data ranges. This allows you to work with table data more easily. For example, the =SUM(Products[Price]) formula calculates the sum of values contained in the Price column ( TableColumn.Name = “Price”) of the Products table (Table.Name = “Products”).
If the Table.ShowHeaders property is set to true , column names are displayed in the header row at the top of the table.
Note
A column name should be unique within the Table.Columns collection.
If you format the specific cell range as a table via the TableCollection.Add method and set the top row of this range to be displayed as the table header (the hasHeaders parameter value is true ), the Name property of each column is automatically set to the string that represents the value of the corresponding cell in the table header.
If any cell in the table header row initially has an empty value, or you do not set the top row of the table range to be displayed as the table header, column names (headers) are set to default values (Column1, Column2, etc.).
| Specified Column Names | Default Column Names |
|---|---|
To hide the table header row (column names), set the Table.ShowHeaders property to false.
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.
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:
Create a Table
Format the Table

Table Header Row
Calculated Column
Table Total Row
