Spreadsheet Rows

Spreadsheet row settings define the behaviours and attributes of rows and their cells, including unique identifiers, row height, styling, and cell properties like read-only status. This section covers methods, events, and settings related to the data grid rows.

What's new in Version 11?

  • Row style: It is possible to define the style index for all cells in the same row.

onbeforeinsertrow Before a new row is inserted. Return false to cancel the user action.
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.
