Attachment.ColumnHidden Property (Access)
You can use the ColumnHidden property to show or hide a specified column in Datasheet view. Read/write Boolean.
The ColumnHidden property applies to all fields in Datasheet view and to form controls when the form is in Datasheet view.
Hiding a column with the ColumnHidden property in Datasheet view doesn't hide fields from the same column in Form view. Similarly, setting a control's Visible property to False in Form view doesn't hide the corresponding column in Datasheet view.
The ColumnHidden property is not available in Design view.
