Summary

For non-editable columns in st.dataframe or st.data_editor I want to display merged cells like the empty cells in the image above.
I want to merge any columns (not necessarily all rows) or any rows (not necessarily all columns).
It's ok if they are separated on selection like in the image below.

Why?

It's just to improve the readability of the table.
But this is very necessary as I want to continue using Streamlit in the future.

How?

It's fine to just remove the separator color for the specified coordinates.
But I can't come up with a concise way to specify the coordinates.

@matsushitaa Thanks for this feature request. Do you have more information on your use case? In which situations do you like to have the cells combined? This might be something that is a bit more likely to be added to st.table.

@lukasmasuch Thank you for your reply.

I'm aiming for a table like the image above.
A table like the image in the middle should be sufficient.
The yellow cells are variables.
The green cells are calculated from the values ​​of the yellow cells.
In reality, there are more than twice as many rows as this.

I'm currently using st.data_editor and it looks like the image below.
I've received requests from users to make it easier to read.

I use st.data_editor more often than st.table and st.dataframe. There are many input fields, so it's very helpful to be able to enter data in st.data_editor.

By the way, st.data_editor allows you to select columns and sort rows, but this breaks the table, so I'd like to disable sorting as well.(#10015)
