vue 甘特圖 vxe-gantt 手動增加一條依賴線，刪除連接線的用法,通過設置 links 定義連接線,from 對應源任務的行主鍵,tom 對應目標任務的行主鍵

0 FinishToStart 結束後才開始，表示一個任務必須在另一個任務開始之前完成
1 StartToFinish 開始到結束，表示從某個過程的開始到結束的整個過程
2 StartToStart 開始後才開始，表示一個活動結束了，另一個活動才能開始，它們之間按先後順序進行
3 FinishToFinish 完成到完成，表示一個任務必須在另一個任務完成之後才能完成

過調用 setTaskLinks、clearTaskLinks 方法來設置或清除連接線可以很簡單的畫連接線或清除連接線
