## ITableSelectControl\ Interface
Provides a fluent API for configuring and running the TableSelect control — a single\-row\-selection table\.
```csharp
public interface ITableSelectControl
```
#### Type parameters
`T`
The type of items displayed as table rows\.
### Remarks
The control renders item data as a paginated table with named columns, optional row
filtering, history persistence, and view\-only mode\. The user navigates rows with the
arrow keys and confirms with `Enter`\. At least one column \([AddColumn\(string, Func<T,object>, Func<object,string>, Nullable<int>, ColumnAlignment, bool\)](ITableSelectControl_T_.md#PromptPlusLibrary.ITableSelectControl_T_.AddColumn(string,System.Func_T,object_,System.Func_object,string_,System.Nullable_int_,PromptPlusLibrary.ColumnAlignment,bool) 'PromptPlusLibrary\.ITableSelectControl\\.AddColumn\(string, System\.Func\, System\.Func\, System\.Nullable\, PromptPlusLibrary\.ColumnAlignment, bool\)')\)
and one item \([AddItem\(T, bool\)](ITableSelectControl_T_.md#PromptPlusLibrary.ITableSelectControl_T_.AddItem(T,bool) 'PromptPlusLibrary\.ITableSelectControl\\.AddItem\(T, bool\)') or [AddItems\(IEnumerable<T>, bool\)](ITableSelectControl_T_.md#PromptPlusLibrary.ITableSelectControl_T_.AddItems(System.Collections.Generic.IEnumerable_T_,bool) 'PromptPlusLibrary\.ITableSelectControl\\.AddItems\(System\.Collections\.Generic\.IEnumerable\, bool\)')\)
must be configured before [Run\(CancellationToken\)](ITableSelectControl_T_.md#PromptPlusLibrary.ITableSelectControl_T_.Run(System.Threading.CancellationToken) 'PromptPlusLibrary\.ITableSelectControl\\.Run\(System\.Threading\.CancellationToken\)') is called, otherwise a
[System\.ComponentModel\.DataAnnotations\.ValidationException](https://learn.microsoft.com/en-us/dotnet/api/system.componentmodel.dataannotations.validationexception 'System\.ComponentModel\.DataAnnotations\.ValidationException') is thrown\.
Every configuration method returns the same [ITableSelectControl<T>](ITableSelectControl_T_.md 'PromptPlusLibrary\.ITableSelectControl\') instance so
calls can be chained \(fluent style\)\. Call [Run\(CancellationToken\)](ITableSelectControl_T_.md#PromptPlusLibrary.ITableSelectControl_T_.Run(System.Threading.CancellationToken) 'PromptPlusLibrary\.ITableSelectControl\\.Run\(System\.Threading\.CancellationToken\)') last\.
### Methods
