# Row Group

Use the [RowGroup](https://datatables.net/extensions/rowgroup/) extension to group
the data according to the content of one colum. Optionally, you can hide the content of that column to avoid duplicating the information.

```{code-cell} ipython3
:tags: [full-width]

import itables

itables.init_notebook_mode()

df = itables.sample_pandas_dfs.get_countries()

itables.show(
    df.sort_values("region"),
    rowGroup={"dataSrc": 1},
    columnDefs=[{"targets": 1, "visible": False}],
)
```
