DataFrame styling doesn't work when it's used as input to another component #9938
Closed as not planned
Description
Describe the bug
When you format a dataframe with pandas Styles, and then use them in gr.DataFrame, the style only applies if the dataframe is not used as input to callbacks or other components.

Reproduction
If I do this:
import gradio as gr
import gradio as gr
import pandas as pd
df = (
pd.DataFrame(
{
"values": [
1.333333333333333,
2.44444444444444444,
3.55555555555555555,
6.77777777777777777,
],
"other_values": [
1.333333333333333,
2.44444444444444444,
3.55555555555555555,
6.77777777777777777,
],
}
)
.style.format({"values": "{:.2f}", "other_values": "{:.0f}"})
.highlight_min("values")
.highlight_max("other_values")
)
with gr.Blocks() as demo:
data = gr.DataFrame(df)
demo.launch()then the table is properly styled as expected:
If I add a Markdown component that takes the dataframe as its input, the styling disappears.
def create_text(df):
n_rows = len(df.index)
return f"# This is some markdown\nThere are {n_rows} rows in the dataframe"
with gr.Blocks() as demo:
data = gr.DataFrame(df)
gr.Markdown(create_text, inputs=[data])Screenshot
