vxe-gantt 如何自定義依賴線的寬度，連接線的寬度大小

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

自定義所有線的寬度

通過設置 task-link-config.lineWidth 自定義連接線的寬度

建議寬度不要超多 5px，不然容易造成渲染樣式過粗疊加到一起
