Some column names have tooltip, such as Storage Memory, Task Time(GC Time), Input, Shuffle Read, Shuffle Write and Blacklisted, but there are still some list names that have not tooltip. They are RDD Blocks, Disk Used,Cores, Activity Tasks, Failed Tasks , Complete Tasks and Total Tasks. oddly, Executors section below,All the column names Contains the column names above have tooltip . It's important for open source projects to have consistent style and user-friendly UI, and I'm working on keeping it consistent And more user-friendly. ### Does this PR introduce any user-facing change?
