# Table Operations

## Kinds of Table Operations

Decision tables can contain thousands of lines and hundreds of columns, to work with such a rule would not be simple and clear. This is especially true when you want to edit certain values and you have to go through all the rows in the table. Because of that, we have added a couple of small, but useful features that will make your work more efficient, there are:

1. \*\*\*\*[**Filter** ](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/table-operations/filter.md)- finds the value in the columns
2. \*\*\*\*[**Sort** ](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/table-operations/sort.md)- sorts the values in the column in ascending/descending order
3. \*\*\*\*[**Preset values**](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/table-operations/valid-values.md) - set of possible values in which can be in the particular columns
4. \*\*\*\*[**Search** ](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/table-operations/search.md)- finds the value in the whole rule (rows)

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 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.decisionrules.io/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/table-operations.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.
