# KeyValue

```gistui
root = KeyValue(plan, cols:2)
plan = |Key|Value
|Plan|Team
|Monthly cost|$348
|Region|EU (Frankfurt)
|Tokens used|612k / 1M
```

## Signature

This is the line a model reads in the system prompt.

```gistui
KeyValue(data:data, cols:num)
```

- **Group:** Data
- **Children:** No
- **Positional arguments:** `data` (a trailing `?` means it may be left out)

## Props

| Prop | Type | How to write it | Notes |
|---|---|---|---|
| `data` | table | positional, required |  |
| `cols` | number | named: `cols:…` |  |

## Use your own component

Keep the name and schema, swap what is drawn. The prompt and the model's output do not change.
