Expanding APIs

Expanding state is stored on the table using the following shape:

export type ExpandedState = true | Record<string, boolean>

export type ExpandedTableState = {
  expanded: ExpandedState
}

export type ExpandedState = true | Record<string, boolean>

export type ExpandedTableState = {
  expanded: ExpandedState
}

toggleExpanded: (expanded?: boolean) => void

toggleExpanded: (expanded?: boolean) => void

Toggles the expanded state (or sets it if expanded is provided) for the row.

getIsExpanded: () => boolean

getIsExpanded: () => boolean

Returns whether the row is expanded.

getIsAllParentsExpanded: () => boolean

getIsAllParentsExpanded: () => boolean

Returns whether all parent rows of the row are expanded.

getCanExpand: () => boolean

getCanExpand: () => boolean

Returns whether the row can be expanded.

getToggleExpandedHandler: () => () => void

getToggleExpandedHandler: () => () => void

Returns a function that can be used to toggle the expanded state of the row. This function can be used to bind to an event handler to a button.

manualExpanding?: boolean

manualExpanding?: boolean

Enables manual row expansion. If this is set to true, getExpandedRowModel will not be used to expand rows and you would be expected to perform the expansion in your own data model. This is useful if you are doing server-side expansion.

onExpandedChange?: OnChangeFn<ExpandedState>

onExpandedChange?: OnChangeFn<ExpandedState>

This function is called when the expanded table state changes. If a function is provided, you will be responsible for managing this state on your own. To pass the managed state back to the table, use the tableOptions.state.expanded option.

autoResetExpanded?: boolean

autoResetExpanded?: boolean

Enable this setting to automatically reset the expanded state of the table when expanding state changes.

enableExpanding?: boolean

enableExpanding?: boolean

Enable/disable expanding for all rows.

getExpandedRowModel?: (table: Table<TData>) => () => RowModel<TData>

getExpandedRowModel?: (table: Table<TData>) => () => RowModel<TData>

This function is responsible for returning the expanded row model. If this function is not provided, the table will not expand rows. You can use the default exported getExpandedRowModel function to get the expanded row model or implement your own.

getIsRowExpanded?: (row: Row<TData>) => boolean

getIsRowExpanded?: (row: Row<TData>) => boolean

If provided, allows you to override the default behavior of determining whether a row is currently expanded.

getRowCanExpand?: (row: Row<TData>) => boolean

getRowCanExpand?: (row: Row<TData>) => boolean

If provided, allows you to override the default behavior of determining whether a row can be expanded.

paginateExpandedRows?: boolean

paginateExpandedRows?: boolean

If true expanded rows will be paginated along with the rest of the table (which means expanded rows may span multiple pages).

If false expanded rows will not be considered for pagination (which means expanded rows will always render on their parents page. This also means more rows will be rendered than the set page size)

setExpanded: (updater: Updater<ExpandedState>) => void

setExpanded: (updater: Updater<ExpandedState>) => void

Updates the expanded state of the table via an update function or value

toggleAllRowsExpanded: (expanded?: boolean) => void

toggleAllRowsExpanded: (expanded?: boolean) => void

Toggles the expanded state for all rows. Optionally, provide a value to set the expanded state to.

resetExpanded: (defaultState?: boolean) => void

resetExpanded: (defaultState?: boolean) => void

Reset the expanded state of the table to the initial state. If defaultState is provided, the expanded state will be reset to {}

getCanSomeRowsExpand: () => boolean

getCanSomeRowsExpand: () => boolean

Returns whether there are any rows that can be expanded.

getToggleAllRowsExpandedHandler: () => (event: unknown) => void

getToggleAllRowsExpandedHandler: () => (event: unknown) => void

Returns a handler that can be used to toggle the expanded state of all rows. This handler is meant to be used with an input[type=checkbox] element.

getIsSomeRowsExpanded: () => boolean

getIsSomeRowsExpanded: () => boolean

Returns whether there are any rows that are currently expanded.

getIsAllRowsExpanded: () => boolean

getIsAllRowsExpanded: () => boolean

Returns whether all rows are currently expanded.

getExpandedDepth: () => number

getExpandedDepth: () => number

Returns the maximum depth of the expanded rows.

getExpandedRowModel: () => RowModel<TData>

getExpandedRowModel: () => RowModel<TData>

Returns the row model after expansion has been applied.

getPreExpandedRowModel: () => RowModel<TData>

getPreExpandedRowModel: () => RowModel<TData>

Returns the row model before expansion has been applied.
