Interactive tables

[maralski]

Problem

I often use interactive tables in ML projects. For example, to annotate a CSV interactively and train an ML model on each update. To achieve this we need the ability to interact with rows in a table. The ability to for example, highlight a table and click a button that has an action associated with it. The action would receive the highlighted row references as input and the program can then carry out any workflow on the rows (i.e. update ML model taking into account new annotated rows).

Solution

I currently use qgrid for this purpose. Would be great if we had a similar widget.

I have a similar use case where I would like to update the content of a secondary dataframe/table based on which row is selected on a primary dataframe. In my case there would ideally be no intermediate button click.

Perhaps there could be a selected_row member on dataframe objects which contains the row number of the selected row? A change would then trigger re-execution of the python code.

Single row selection is what I would need but it sounds like @maralski is asking for multi row selection which only triggers an update with a button click?

Yes I would need multi row with button click otherwise it would force update per row selection which is probably going to be inefficient.

If you want to select rows in a table, you can use this somewhat inelegant workaround, which will scale up to about 1000 rows or so. 👍

Thanks. I came up with a similar workaround but it felt unnatural :(

Is there any roadmap for more qgrid-like features? I'm using single and multi-row selection, row filtering and column reordering a lot and find them essential. Not having these in streamlit is a serious blocker for me. Any workarounds like above are real obstacles and are considered weird/cumbersome at best, and lead to sticking with alternatives like qgrid otherwise.

Closing this, as this appears to exist as a custom component. If I'm misunderstanding this issue, please let me know and I'm happy to reopen
