Hello,

I am working on trying to implement tooltips for my DataTable and I found out how to link tooltips to the headers, but I want it to be if I hover over a specific cell in a column then the tooltip displays data from another column. How do I do this?

app.layout = dash\_table.DataTable(  
data=df.to\_dict(‘records’),  
columns=[{‘id’: c, ‘name’: c} for c in df.columns],

```
tooltip_header={i: i for i in df.columns},

# Style headers with a dotted underline to indicate a tooltip
style_header={
    'textDecoration': 'underline',
    'textDecorationStyle': 'dotted',
},

```

Hi @ttucker34 and welcome to the Dash community 🙂

I recommend using [Dash AG Grid](https://dash.plotly.com/dash-ag-grid) instead of DataTable. Here’s a tutorial showing some of the amazing things you can do with Tooltips in the grid (including examples showing data from other columns in the tooltip):
