Struct TableState 

pub struct TableState {
    pub headers: Vec<String>,
    pub rows: Vec<Vec<String>>,
    pub selected: usize,
    /* private fields */
}

State for a data table widget.

Pass a mutable reference to Context::table each frame. Up/Down arrow keys move the row selection when the widget is focused. Column widths are computed automatically from header and cell content.

Fields

headers: Vec<String>

Column header labels.

rows: Vec<Vec<String>>

Table rows, each a Vec of cell strings.

selected: usize

Index of the currently selected row.

Implementations

impl TableState

pub fn new( headers: Vec<impl Into<String>>, rows: Vec<Vec<impl Into<String>>>, ) -> Self

Create a table with headers and rows. Column widths are computed immediately.

pub fn set_rows(&mut self, rows: Vec<Vec<impl Into<String>>>)

Replace all rows, preserving the selection index if possible.

If the current selection is beyond the new row count, it is clamped to the last row.

pub fn selected_row(&self) -> Option<&[String]>

Get the currently selected row data, or None if the table is empty.
