Add Task
You can add tasks in different ways:
addTasks (data: number | ITaskData | ITaskData[] = 1, level?: number): GC.Spread.Sheets.GanttSheet.Task[];
insertTasks (taskNumber: number, data: number | ITaskData | ITaskData[] = 1, level?: number): GC.Spread.Sheets.GanttSheet.Task[];
Remove Task
Tasks can also be removed in different ways:
removeTasks (taskNumbers: number | number[]): void;
removeTasksByRange (taskNumber: number, count = 1): void;
Indent/Outdent Task
You can also indent tasks with specific API:
indentTasks (taskNumbers: number | number[]): void;
indentTasksByRange (taskNumber: number, count = 1): void;
outdentTasks (taskNumbers: number | number[]): void;
outdentTasksByRange (taskNumber: number, count = 1): void;
