# How to set column visibity

## Overview

In this step-by-step guide, we will explore configuring a column within the [**Avonni Data Table**](/flow/flow-components/data-table.md) component, based on particular criteria. We’ll demonstrate how you can effectively use flow variables to define these criteria, enabling a more dynamic and tailored presentation of your data within the table according to the specific conditions or requirements you set.

## Guided Steps

### Creating your flow Variable

That will be used as a variable to show or hide a column.

{% hint style="info" %}
***As an example***

**Example Formula:**

`{!Account.Industry}='Technology'`

**Implementation:**

Create a formula to determine if an Account's Industry field is 'Technology', and display a column in the Avonni Data Table accordingly, allowing users to view information relevant to Technology industry accounts only.
{% endhint %}
{% endstep %}

{% step %}

### Configuring the Data Source

To populate the Avonni Table, a Data Collection is required. You can achieve this by establishing a 'Get Records' collection.
{% endstep %}

{% step %}

### Drag the columns

Once your Data Source is configured, use it as a Data Collection to enable dragging columns derived from the 'Get Records' collection onto the Data Table.
{% endstep %}

{% step %}

### Activate the Hidden variable

* Open the '**Properties Panel**' and go to '**Data Source selection**' on the Avonni Data Table.
* Click on the desired column.
* Find the '**Hidden**' attribute and click the formula icon.
* Select '**Mapped**'.
* Choose your pre-created variable or formula to assign visibility. For example, if you have a variable named 'isVisible' with values true or false, select it here.

## 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.avonnicomponents.com/flow/tutorials/components/data-table/tips-and-tricks/how-to-set-column-visibity.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.
