Add static_columns param for interactive dataframes

[hannahblair]

Description

Adds a static_columns param, which takes a list of ints or strs to reference the columns. The use of static rows does feel potentially quite niche so we'll see if there are any requests for that.

Closes: #2020

I was thinking a padlock somewhere in the cell but it just looks too crowded.

sgtm

The current behavior doesn't seem to work well with adding/deleting columns.

It depends on the use case, but for example, even if there is a column that the app developer wants to prevent users from changing, users can make it editable by adding a new column to its left.

import gradio as gr
import numpy as np

with gr.Blocks() as demo:
    gr.Dataframe(value=np.arange(15).reshape(3, 5), static_columns=[1], interactive=True)
demo.launch()

0.mp4

[abidlabs]

great catch @hysts. Perhaps we'll need to add some logic that if static_columns is specified, then col_count is fixed and columns cannot be inserted/deleted at all

[hannahblair]

hmm I see. alternatively, we could remove the specified static column from static_columns if it's removed. but adding columns will also cause some confusing behaviour. i've updated the PR to set it to "fixed" if static columns are specified. thanks for reviewing @hysts!

[abidlabs]

I reran @hysts's repro and I'm seeing a different issue with cell / header alignment being off:

import gradio as gr
import numpy as np

with gr.Blocks() as demo:
    gr.Dataframe(value=np.arange(15).reshape(3, 5), static_columns=[1], interactive=True)
demo.launch()

[hannahblair]

@abidlabs fixed! my bad python code was the culprit

[abidlabs]

Nice @hannahblair lgtm! We could consider adding a padlock symbol just in the header cell to designate a static column, but we don't have to do it now (or ever if it's a bad ui)

[hannahblair]

@abidlabs agreed, I'm happy with this now!
