# Table Window

The new Excel Filter added to the TableWindow control adds a new powerful functionality to existing applications with the simple setting of the AllowFiltering property.

Once the filtering functionality is enabled, users will see the drop down button appear next to the column name when hovering over the column with the mouse.

Pressing the button shows a drop down form, very similar to Excel's filter window, pre-filled with the values of the column. The user can turn on or off the value to use to filter the rows of the table window.

In addition to the simple check boxes filter, there is a more powerful text filter available to users, where it's possible to enter custom values and filtering rules:

The filtering form is already automatically localized to the local language.

## Customization

The filtering functionality is fully customizable programmatically. You can find the relevant information in the C1 help system available online from our download pages.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.iceteagroup.com/general/framework/extensions/table-window.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
