# 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.
