Is the Rows field required to build a functioning editable grid using a!gridLayout?

In the context of building an editable grid using the a!gridLayout function, the Rows field is indeed essential. The Rows field serves as the core element that defines the data displayed within the grid. It specifies the individual records that will populate each row of the grid, allowing users to see and interact with the data.

Without providing a Rows field, the grid would not have any data to display or edit, making it impossible for users to utilize the editable features of the grid. This requirement is particularly crucial when considering the nature of the grid, as the purpose of an editable grid is to allow modifications to the underlying data displayed in its rows.

Other options suggest various scenarios where the Rows field might not be needed or is optional, but within the functionality of the a!gridLayout, the necessity of defining the Rows field remains constant at all times to ensure the grid performs as intended.
