# Timeline

**Package:** `flyte.report`

Append a best-effort chronological timeline to a tab of the task report.

Writes are skipped silently when there is no active report (running locally, or the
task was not created with ``report=True``), so rendering a timeline never breaks the
work it is observing.

## Parameters

```python
class Timeline(
    tab_name: str,
)
```
| Parameter | Type | Description |
|-|-|-|
| `tab_name` | `str` | |

## Methods

| Method | Description |

| [`heading()`](#heading) |  |
| [`row()`](#row) |  |

### heading()

def heading(
