FrameDisplay is a lightweight Python package for rendering Pandas DataFrames as interactive HTML tables within Jupyter Notebooks and JupyterLab. It improves the default DataFrame display by adding features such as resizable columns, client-side sorting, sticky headers and index for improved navigation, data type indicators in column headers, distinct styling for null values, and tooltips for viewing complete cell content.

I work extensively with Pandas in my personal projects and have always wanted something similar to Databricks' display function, but for Jupyter. The existing open-source alternatives were either too heavyweight, lacked the visual appeal or didn't check all the boxes I needed. So I built this package to bridge that gap. It's not perfect yet, but I like it more than the alternatives :)


Live demo: [CodePen](https://codepen.io/B-L-A-Z-E/pen/empJPKV)

## Features

- **Resizable Columns**: Drag column dividers to resize them.
- **Sortable Columns**: Click on column headers to sort the data.
- **Sticky Header & Index**: The header and index rows remain visible during vertical and horizontal scrolling.
- **Column Type Icons**: Icons in headers indicate data types (numeric, string, etc.).
- **Null Value Styling**: `null` values are visually distinct.
- **Tooltips**: Hover over cell content to see the full value.
- **No Size Limit**: Display DataFrames of any size (be mindful of browser performance with very large tables).
- **Customizable Themes**: Choose from several built-in themes or add your own CSS.

**Roadmap**
- Virtual scrolling for improved performance with very large DataFrames.
- Additional customization options (e.g., theming).

## Installation

```bash
pip install framedisplay
```

## Usage

To display a DataFrame, simply import `framedisplay` and use the `frame_display` function:

```python
import pandas as pd
import numpy as np
import framedisplay as fd

df = pd.DataFrame({
    'Name': ['Alice', 'Bob', np.nan],
    'Age': [25, np.nan, 35],
    'Score': [95.5, 87.2, np.nan]
})

fd.frame_display(df)
```

You can also enable FrameDisplay globally for all DataFrames in Jupyter by calling `fd.integrate_with_pandas()`:

```python
import pandas as pd
import framedisplay as fd

# Enable FrameDisplay for all DataFrames
fd.integrate_with_pandas()

# This will now display using FrameDisplay
df
```

## How it Works

FrameDisplay renders your Pandas DataFrame into an HTML table and injects custom CSS and JavaScript to enable interactive features directly in your Jupyter Notebook or browser.

## Configuration Options

FrameDisplay uses global configuration (`window.FrameDisplayConfig`) that applies to all future table renderings in the notebook/browser session. Once you set a configuration option, it persists until you explicitly reset it or change it.


```python
import framedisplay as fd

fd.configure({
    'theme': 'dark',
    'enableSorting': False
})

# All subsequent calls use this config
fd.frame_display(df1)
fd.frame_display(df2)
```

You can also pass configuration options directly to `frame_display()`:

```python
fd.frame_display(df1, config={
    'theme': 'ocean',
    'enableSorting': False
})
```

To reset the global configuration to defaults, call `configure()` with `reset=True`:
```python
fd.configure(reset=True)
```

### Themes

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `theme` | string | `''` | Built-in theme: `'dark'`, `'ocean'`, `'sunset'`, `'neon'`, `'minimal'`, `'contrast'` |
| `customCSS` | string | `''` | Additional CSS rules to append after base styles |

### Behavior Options

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `autoInit` | boolean | `true` | Automatically initialize on page load |
| `ReInitialize` | boolean | `false` | Force reprocessing of all existing tables with new config |
| `tableSelector` | string | `'.frame-display-table'` | CSS selector for tables to process |
| `minColumnWidth` | number | `30` | Minimum column width in pixels |

### Feature Toggles

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `enableResizing` | boolean | `true` | Enable column resizing by dragging column dividers |
| `enableSorting` | boolean | `true` | Enable sorting by clicking column headers |
| `enableTooltips` | boolean | `true` | Show full cell content on hover |
| `enableStickyHeader` | boolean | `true` | Keep header row visible when scrolling vertically |
| `enableStickyIndex` | boolean | `true` | Keep index column visible when scrolling horizontally |


## Offline Mode

If you are working in an environment without internet access, you can inject the necessary JavaScript and CSS locally by calling `initialize()` at the start of your notebook. This bundles the required assets into the notebook itself.

```python
import framedisplay as fd
fd.initialize()

# Now you can use fd.frame_display(df) without needing an internet connection
```
