Adding Data

Once your columns are set up, you populate the table by adding lines and setting cell data. Each line is a row that holds one cell per column. Lines are referenced by opaque LineId handles, which you get back when creating a line and use to read or modify it later.

Lines

Lines are rows in the table. Each line holds one cell per column.

#![allow(unused)]
fn main() {
let row = table.new_line(None); // None = no parent (top-level row)
table.line_mut(row).data_set(0, "sda").data_set(1, "100G");
}

The data_set calls are chainable. Column indices are zero-based and match the order columns were added.

Reading data back

#![allow(unused)]
fn main() {
let name = table.line(row).data_get(0); // Some("sda")
let missing = table.line(row).data_get(99); // None
}

Cells

Each cell can also carry metadata:

#![allow(unused)]
fn main() {
let line = table.line_mut(row);
line.cell_mut(0).unwrap().style_set(CellStyle::new().fg(Color::Red));
line.cell_mut(0).unwrap().uri_set("https://example.com");
}

Line handles

new_line returns a LineId — an opaque handle. You can’t construct one by accident, which prevents indexing bugs.

Iterating

You can walk over all lines in the table, or just the root lines (those without a parent). This is useful for filtering, exporting, or building a second table from an existing one.

#![allow(unused)]
fn main() {
// All lines
for id in table.line_ids() {
    let data = table.line(id).data_get(0);
}

// Root lines only (no parent)
for id in table.root_line_ids() {
    // ...
}
}
