Improvement of the FunctionTable page #5

Currently, the FunctionTable page looks as below

We need to make some improvements on this page:

• Align the columns Status and Options to the right of the table. And make the contents of these two columns compactly display.
• Add a new option in Options columns: Start or Stop. When the function is running, the available options are Trigger | Detail | Stop | Delete. And when the function is down, the available options are Trigger | Detail | Start | Delete.
• Write a mock API test to output both running function and down function in the function table.
