# Column Group

Just like in Microsoft Excel, **Column Grouping** in Wave lets you visually group multiple columns under a single header. This makes large datasets easier to scan, organize, and manage—especially when working with complex or related information.

## What is Column Grouping?

Column grouping allows you to:

* Combine related columns under a shared group header
* Assign colors and tooltips for better visual guidance
* Expand or collapse grouped columns to save space

## How to Create a Column Group

1. **Click on *****Column Group***
   * Available from the toolbar and column header dropdown.
2. **Select Columns to Group**
   * Choose columns to group.
3. **Pick a Group Color**
   * Assign a color to help visually differentiate groups.
4. **Choose a Group Style** *(Optional)*
   * Select a style to further customize how your grouped columns appear.
5. **Add a Tooltip** *(Optional)*
   * Add helpful text that appears when users hover over the group’s expand/collapse icons.
6. **Click *****OK***** to Apply**
   * Your grouped columns will now display with a shared colored header and toggle icons.

## Add More Columns to a Group

Use the **+ Add New** icon to add new columns. You can follow the same steps above to include them in a group.

### Tips:

* Hover over the expand/collapse icons to see the tooltip you added.
* You can create multiple column groups in a single grid.
* Grouped columns make your grid look cleaner and are great for reporting views!
