the doc on the styles argument of render.DataGrid() is incorrect: snake-case works

[shrektan]

It says:

style: A dictionary of CSS properties and values to apply to the selected rows and columns. The keys must be camelCased CSS property names to work properly with react.js (e.g. backgroundColor instead of background-color).

However, the following code works.

...
styles = [
  {
      "style": {"text-align": "center"},
  },
  {
      "cols": num_cols_idx,
      "style": {"text-align": "right"},
  },
  {
      "rows": list(range(1, df.height, 2)),
      "style": {"background-color": "#f9f9f9"},
  },
]
return render.DataGrid(df, filters=True, styles=styles)  # type: ignore
