On the Streamlit roadmap page, I read:

Selections on dataframes Launched
Catch click events on tables and do something with them in your app!

However, on the Streamlit documentation page, I don’t see a parameter like “on_click” for a callback function.
Is it my mistake?
Thanks!

I believe it is the on_select parameter that can take the callable value. Also there is selection_mode to define what to do when a selection is triggered.

I use ag-Grid to catch mouse events on a DataFrame. Look at this example: Cookbook. I was thinking of a similar function, but without the need for JavaScript.

Hello!

I don’t know if anyone has experienced this issue. Since I upgraded to 1.36, some of my dataframes do not show properly. I keep getting the below error in my app. Is there any reason for this or a way to fix this?

Edit: This majorly happens to dataframes with more than 10 rows.
Edit 2: Current observation is that that this happens when you wrap the dataframe in an st.column or in an st.container

Thank you
