[FEATURE] add BaseTable tool for convenience

**Is your feature request related to a problem? Please describe.**
in most occasions, we have fixed fields in every table like id/create_at/updated_at etc. in our code, it's like

```

class BaseModel:
id: str
created_at: int
updated_at: int

class User(BaseModel):
name: str
email: str
# ...

class Project(BaseModel):
name: str

```

think its better to have a tool that contains some fixed fields definition in order to be inherited by other tables

**Describe the solution you'd like**

1、add a tab `BaseTable` or `MetaTable` at tool bar, so user can create custom base tables and define fields here

2、add a `inherit from` button after `add index` and `add field`，click it then we can choose which base table to inherit
