Data Table

Tabular data display with sorting and filtering.

Quick Start

# Run the demo
cargo run -p presentar --example apr_ald_display

Loading .ald Files

use presentar_widgets::{load_ald_as_card, AldDatasetExt};
use presentar_yaml::formats::AldDataset;

// Load from bytes
let data_card = load_ald_as_card(&ald_bytes, "my_dataset")?;
println!("Dataset: {}", data_card.get_name());
println!("Columns: {}", data_card.column_count());

// Or use extension trait
let dataset = AldDataset::load(&ald_bytes)?;
let card = dataset.to_data_card("custom_name");

Verified Test

#[test]
fn test_data_table_sorting() {
    // Table sorting algorithm
    #[derive(Debug, Clone)]
    struct Row {
        name: String,
        age: u32,
    }

    let mut rows = vec![
        Row { name: "Carol".to_string(), age: 35 },
        Row { name: "Alice".to_string(), age: 30 },
        Row { name: "Bob".to_string(), age: 25 },
    ];

    // Sort by name ascending
    rows.sort_by(|a, b| a.name.cmp(&b.name));
    assert_eq!(rows[0].name, "Alice");
    assert_eq!(rows[1].name, "Bob");
    assert_eq!(rows[2].name, "Carol");

    // Sort by age descending
    rows.sort_by(|a, b| b.age.cmp(&a.age));
    assert_eq!(rows[0].age, 35);
