onbeforeinsertrow(worksheet: Object, rows: Object[]) => Boolean | Object[] | void
oninsertrow After a new row is inserted.
oninsertrow(worksheet: Object, rows: Object[]) => void
onbeforedeleterow Before a row is deleted. Return false to cancel the user action.
onbeforedeleterow(worksheet: Object, rows: Number[]) => Number[] | Boolean | void
ondeleterow After a row is deleted.
ondeleterow(worksheet: Object, rows: Number[]) => void
onmoverow After a row is moved to a new position.
onmoverow(worksheet: Object, origin: Number, destination: Number) => void
onresizerow After the height changes for one or more rows.
onresizerow(worksheet: Object, row: Mixed, height: Mixed, oldHeight: Mixed) => void
onchangerowvisibility When the visibility of rows changes.
onchangerowvisibility(worksheet: Object, state: boolean: affected: []]) => void

Initial Settings

The following row-related properties are available through the spreadsheet initialization.

Property Description
allowInsertRow: boolean Enable the user to enter new rows. Default: true
allowManualInsertRow: boolean A new row is automatically inserted when the user presses the enter key in the last row. Default: true

rowDrag: boolean Allow the user to change the position of one row by dragging and dropping. Default: true
rowResize: boolean Allow the user to resize rows. Default: true
defaultRowHeight: number The default row height.
minSpareRows: number The mandatory number of blank rows at the end of the spreadsheet. Default: none.

Available properties

It is possible to initialize the spreadsheet with a custom id, text and height using the following properties:

Property Description
id: number Unique identifier for the row, which can be used to synchronize the content with a database.
height: number The height of the row in pixels.
