Functional Highlights
1. Permission control When we first start running, we first hide all the menus on the main interface of the system. After the user fills in the user name and password and passes the user name and password, according to the permissions of the logged in user, the logged in user can operate menu items are displayed.
2. Temporary salary table Because the fields of the salary table may change, and the salary tables of different companies may also be different, we only preset 25 fields in the temporary salary table.
