**AgGrid** is an awesome grid for web frontend. More information in [https://www.ag-grid.com/](https://www.ag-grid.com/). Consider purchasing a license from Ag-Grid if you are going to use enterprise features!

Current AgGrid version is [34.3.1](https://www.ag-grid.com/archive/34.3.1/)

# Install

```
pip install streamlit-aggrid

```

# Quick Use

Create an example.py file

```python
from st_aggrid import AgGrid
import pandas as pd

df = pd.read_csv('https://raw.githubusercontent.com/fivethirtyeight/data/master/airline-safety/airline-safety.csv')
AgGrid(df)
```

Run :

```shell
streamlit run example.py
```

# Demo

Grid data is sent back to streamlit and can be reused in other components. In the example below a chart is updated on grid edition.

> v1.0.0 breaks compatibility with previous versions and many people reached me to say that it is unstable.  
> Main changes are on gridReturn object as I'm moving heavy processment to python side.  
> I'm working to stabilize it, if you find any issues, please open a topic on the issue tracker  
> with a reproductile example, if possible.  
> Meanwhile use the last v.0.3.4 if things are not working for you! I hope to have everything fixed soon.

Version 0.3.5

- Added quickfilter
- Added Excel Export Module
- Bugfixes (an probably introduced new ones :/)
- Code cleanup
- Updated Ag-Grit to 29.1.0 (including ag-grid-react) which will cause direct HTML returns to stop rendering ([#198](https://github.com/PablocFonseca/streamlit-aggrid/issues/198)). Use a [cellRenderer](https://www.ag-grid.com/javascript-data-grid/component-cell-renderer/) instead.

- gridOptions may be loaded from file paths or strings
- gridReturn is now a @dataclass with rowIndex added to selected_rows, (previous version returned only the selected data, now you can know which row was selected)
- Changed GridReturnMode behavior. Now update_on accepts a list of gridEvents that will trigger a streamlit refresh, making it possible to subscribe to any [gridEvent](https://www.ag-grid.com/javascript-data-grid/grid-events/).
