# Filter Values

Finds the value in the columns

## Filter Values in Decision Table

Filtering values in a decision table allows you to narrow down rows based on the values in a particular column. This is especially useful when working with large datasets.

{% hint style="success" %}
Filtering is **case-insensitive** and supports **partial matches**. For example, if you filter by "2", it will match values like "120", "240", and "2+4".
{% endhint %}

## How to Apply Filters

1. **Access Filters**: Click the arrow icon in the header of the column you want to filter, then select **Filter Values**.
2. **Set Filter Expressions**:\
   A filter input field will appear where you can add one or more filter expressions. Simply type your expression and press **Enter** to apply it.
   * To remove a filter, click the cross icon next to the expression.
3. **Confirm Filters**:\
   Once your filters are set, confirm them by either clicking outside the filter modal or pressing the **Esc** key.

## Managing Filters

* You can apply filters to multiple columns simultaneously.
* When a column has an active filter, a filter icon will appear in the column header. Clicking this icon will reopen the filter input.
* To clear all filters, click the cross icon at the end of the filter input field.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.decisionrules.io/doc/rules/decision-table/decision-table-designer/table-operations/filter.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
