链接线模式
GanttSheet有三种模式（GC.Spread.Sheets.GanttSheet.TaskBarLinkMode）：
toEnd（朝末端连接）
toTop（朝前端连接）
noLinks（不连接）
任务条高度
您可以使用特定的数字更改任务条的高度：
日期格式
如果向任务条添加文本，您可以更改其显示格式。
可用的格式化选项：
"yyyy-mm-dd"
"yy/m/dd hh:mm"
"yy/m/dd"
"yyyy/m/dd"
"yyyy mmmm dd hh:mm"
"yyyy mmmm dd"
"mmm dd hh:mm"
"'yy mm dd"
"mmmm dd"
"mmm dd"
"ddd yy/m/dd hh:mm"
"ddd yy/m/dd"
"ddd yy mm dd"
"ddd hh:mm"
"ddd mm dd"
"ddd m/dd"
"ddd dd"
"m/dd"
"dd"
"hh:mm"
将任务条圆整到整天
实际任务持续时间并非始终为整天，因此有一个选项可以将这些任务条圆整到整天：
