Initialization
SpreadJS GanttSheet supports using a DataManager View
as a data source.
To use the GanttSheet, add the js file link into the document's head section:
Then you can use the DataManager with the hierarchy schema:
You can then define the correct hierarchy schema based on your source data structure.
Then initialize a GanttSheet.
Batch Mode
The project data records in a GanttSheet are structured data, so batch mode should be used.
Gantt Column
GanttSheets have a property called enableGanttColumn that controls whether to show the gantt column.
By default, this option is true. If you don't want to show it, you can set this property to false when you create GanttSheet or call ganttSheet.bindGanttView(view, { enableGanttColumn: false }).
