Struct TableState 

pub struct TableState {
    pub selected: Option<usize>,
    pub hovered: Option<usize>,
    pub offset: usize,
    /* private fields */
}

Mutable state for a Table widget.

Fields

selected: Option<usize>

Index of the currently selected row, if any.

hovered: Option<usize>

Index of the currently hovered row, if any.

offset: usize

Scroll offset (first visible row index).

Implementations

impl TableState

pub fn select(&mut self, index: Option<usize>)

Set the selected row index, resetting offset on deselect.

pub fn with_persistence_id(self, id: impl Into<String>) -> Self

Create a new TableState with a persistence ID for state saving.

pub fn persistence_id(&self) -> Option<&str>

Get the persistence ID, if set.

impl TableState

pub fn undo_id(&self) -> UndoWidgetId

Get the undo widget ID.

This can be used to associate undo commands with this state instance.

pub fn sort_column(&self) -> Option<usize>

Get the current sort column.

pub fn sort_ascending(&self) -> bool

Get whether the sort is ascending.

pub fn set_sort(&mut self, column: Option<usize>, ascending: bool)

Set the sort state.

pub fn filter(&self) -> &str

Get the filter text.

pub fn set_filter(&mut self, filter: impl Into<String>)

Set the filter text.
