Problem Description
Search optimization of Exchangis1.0 task library table.

Description
When selecting a library table, you need to have a search box, otherwise there are too many library tables to find the desired library table; At the same time, it is necessary to add a covered loading box when loading library table information.
一选择库表的时候，需要有一个搜索框，不然库表太多很难找到想要的库表；同时，加载库表信息还是要加个遮盖的加载框
