Table variable names do not have to be valid MATLAB identifiers. They can include spaces and nonASCII characters, and can start with any character.
Add a variable name with spaces and a dash to T. Then index into T using variable names.
T = addvars(T,SelfAssessedHealthStatus,'NewVariableNames','Self-Assessed Health Status');
T(1:5,{'Age','Smoker','Self-Assessed Health Status'})

Specify Data Type Subscript
Instead of specifying variables using names or numbers, you can create a data type subscript that
matches all variables having the same data type.
First, create a data type subscript to match numeric table variables.
S = vartype('numeric')
S =
table vartype subscript:
Select table variables matching the type 'numeric'
See Access Data in a Table.
Create a table that has only the numeric variables, and only the first five rows, from T.
