Is it possible execute create table from management portal?

I tried this:

CREATE TABLE SQLUser.Teste(ID INT NOT NULL, coluna1 VARCHAR(255), coluna2 VARCHAR(255), coluna3 VARCHAR(255), coluna4 VARCHAR(255)CONSTRAINT TestePK PRIMARY KEY (ID))

Error message:

Set cdef = ##class(%Dictionary.ClassDefinition).%OpenId(table)
Set count = cdef.Properties.Count()
For i = 1:1:count {
Write cdef.Properties.GetAt(i).Name, " ", cdef.Properties.GetAt(i).Type, "", <MY QUESTION>,!
}

How can I do to get maxlen?
