本人想做一个甘特表格控件，主要实现如下功能：
1、表头为相关任务列和显示日期类形式（分月、周、日、时），
2、内容以甘特图一样显示计划和进度相关信息，根据计划开工和结束日期、计划时长 和实际开工和结束日期、实际时长画出开发甘特图内容，并以不同颜色标色，是否延误、是否提前等信息。
3、当鼠标移动到某个任务图上时显示相关完整的任务信息，如计划开工和结束日期、计划时长，实际开工和结束日期、实际时长、当前状态，计划数量、完成数量等。
目前第一步表头已实现，第二步简易实现，未获取数据库信息实现，第三步又怎么实现？本人贴出控件全部代码，希望能够得到朋友们的支持，谢谢。
一、自定义控件第一类表头，表头刻度是以每天按小时分段显示，可调整刻度数
二、自定义控件第二类表头，表头是以每天分段显示。
三、自定义控件第三类表头，表头刻度是以按周分段显示。
