Properties

autoSize → ColumnAutoSize?: Best-fit behavior used when the user double-clicks this column's separator. Set to null to disable double-click best fit.
final
autoSizeWidth → double?: Preferred header content width used by best-fit sizing.
final
autoSizeWidthBuilder → ColumnAutoSizeWidthBuilder?: Computes a preferred header content width for custom widgets. Takes precedence over autoSizeWidth.
final
canHide → bool: Whether this column can be hidden by the user in the column visibility dialog or in the column menu. Defaults to true.
final
combinedColumns → int?: The number of columns that this header column combines into a single header column.
final
filterable → bool: Whether users can filter this leaf column from its header menu.
final
filterType → TreeDataTableColumnFilterType: Filter editor to show when filterable is true.
final
flex → double?: The flex factor to determine how much space this column should take relative to others. If set, the column will expand to fill available space according to its flex value.
final
hashCode → int: The hash code for this object.
no setterinherited
height → int: The height of the header column. Defaults to 55
final
maximumWidth → double?: The maximum width of the header and data column.
final
minimumWidth → double?: The minimum width of the header and data column. Defaults to 50.0.
final
pinLeft → bool: All rows for this column will be pinned to the left
final
pinRight → bool: All rows for this column will be pinned to the right
final
reorderable → bool: Whether users can drag this header column to reorder it.
final
resizable → bool: A flag indicating whether the column is resizable by the user. Defaults to true.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sortable → bool: Whether users can sort this leaf column from its header or column menu.
final
sortComparator → TreeDataTableSortComparator?: An optional comparator for this column's cell sort values.
final
textVisibilityDialog → String: The text to be displayed in the column visibility dialog.
final
visible → bool: A flag indicating whether the header column should be hidden
final
widget → Widget: The widget to be displayed in the header column
final
width → double?: The width of the header and data column.
