内置样式规则
每种任务条类型（GC.Spread.Sheets.GanttSheet.TaskbarStyleRuleName）都有几个内置样式规则。
durationOnly
durationOnlyMilestone
finishOnly
finishOnlyMilestone
manualMilestone
manualProgress
manualSummary
manualTask
milestone
progress
projectSummary
startOnly
startOnlyMilestone
summary
task
特定任务条样式只对含有主键的任务生效。
您可以获取任务的样式并更改其样式属性，如下所示：
/*REPLACE_MARKER*/
/*DO NOT DELETE THESE COMMENTS*/
