CellEdit

@Immutable

data class CellEdit<T>(val item: T, val rowKey: Any, val columnKey: String, val oldText: String, val newText: String)(source)

A committed cell edit, handed to DataTable's onCellEdit.

The table never mutates your data: it reports the edit and waits for you to apply it and pass the updated items back. That keeps a single source of truth in your model, which is what makes undo, dirty tracking, and server round-trips possible at all.

Only edits that actually change the text are reported — committing a cell you did not alter fires nothing.

Constructors

CellEdit

constructor(item: T, rowKey: Any, columnKey: String, oldText: String, newText: String)

Properties

columnKey

val columnKey: String

DataTableHeader.key of the edited column.

item

val item: T

The row item that was edited.

newText

val newText: String

The text the user committed. Parsing it back into your model's type is the caller's job — pair it with DataTableHeader.validateEdit so an unparseable value never reaches here.

oldText

val oldText: String

The cell's text before the edit, as the editor was seeded with it.

rowKey

val rowKey: Any

Key of that row, as produced by DataTable's itemKey.
