See Columns.

	`procedure SetRows(const Value: TRbwDataGridRows);`
See Rows.

	`function ShouldAdujstColWidths(ACol: integer): boolean; override;`

	`function CollectionItem(const ACol, ARow: Longint): TCustomRowOrColumn; override;`
`CollectionItem` returns Rows[ARow].

	`function ColumnOrRow: integer; override;`

	`function ColorSelectedRowOrColumn(ACol, ARow: integer): boolean; override;`

	`function CreateColumns: TAutoAdjustColumns; dynamic;`
`CreateColumns` creates and returns an instance of TAutoAdjustColumns.

	`function CreateRows: TRbwDataGridRows; dynamic;`
`CreateRows` creates and returns an instance of TRbwDataGridRows.

	`function GetFixedRows: integer; virtual;`
See FixedRows.

	`function IsCaptionCell(ACol, ARow: integer): boolean; override;`

	`procedure AdjustColWidths(const ACol: integer); override;`
`AdjustColWidths` is used to calculate the width of the cell required to fit the text in the cell. If AutoAdjustColWidths is true, `AdjustColWidths` is used to change the width of the columns.

	`procedure AdjustRowHeights(const ARow: integer); override;`

	`procedure ColumnMoved(FromIndex, ToIndex: Longint); override;`
`ColumnMoved` adjusts Columns when the user moves a column.

	`procedure Loaded; override;`
`Loaded` sets the FixedCols and FixedRows and calls AdjustColWidths for each column.

	`procedure RowMoved(FromIndex, ToIndex: Longint); override;`
`RowMoved` adjusts Rows when the user moves a row.

	`procedure SetFixedRows(const Value: integer); virtual;`
See FixedRows.

	`procedure SizeChanged(OldColCount, OldRowCount: Longint); override;`
`SizeChanged` adds or removes items in Columns and Rows if the number of columns or rows changes.

	`procedure BeginUpdate; override;`

	`procedure EndUpdate; override;`

	`constructor Create(AOwner: TComponent); override;`

	`destructor Destroy; override;`
`Destroy` destroys the grid. Don't call `Destroy` directly. Call Free instead.

	`procedure DeleteColumn(ACol: Longint); override;`

	`procedure DeleteRow(ARow: Longint); override;`

	`procedure InsertColumn(ACol: Integer); override;`
Use `InsertColumn` to insert a column at position ACol.

	`procedure InsertRow(ARow: Integer); override;`
Use `InsertRow` to insert a row at position ARow.
