在 MATLAB Online 中打开

% Create table
LastName = ["Sanchez";"Johnson";"Zhang";"Diaz";"Brown"];
Age = [38;43;38;40;49];
Smoker = [true;false;true;false;true];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];
patients = table(LastName,Age,Smoker,Height,Weight,BloodPressure)
patients = 5×6 table
    LastName     Age    Smoker    Height    Weight    BloodPressure
    _________    ___    ______    ______    ______    _____________

    "Sanchez"    38     true        71       176       124     93  
    "Johnson"    43     false       69       163       109     77  
    "Zhang"      38     true        64       131       125     83  
    "Diaz"       40     false       67       133       117     75  
    "Brown"      49     true        64       119       122     80  
cellfun(@ (x) fprintf('%s: %s\n', x, class(patients.(x))), patients.Properties.VariableNames)
LastName: string
Age: double
Smoker: logical
Height: double
Weight: double
BloodPressure: double

Interpreting the question in the same way as Chunru, you can also do summary(patients) or varfun(@class, patients) to get the classes of each variable in a table.

If you're asking what types are allowed as table variables, it's essentially anything in MATLAB that behaves like an array. That is, scalar-only types cannot be table variables (but they can be put in a cell array and that cell array can be a table variable). The table doc specifies, "Common input variables are numeric arrays, logical arrays, character arrays, structure arrays, or cell arrays. Input variables also can be objects that are arrays. Such an array must support indexing of the form var(index1,...,indexN), where index1 is a numeric or logical vector that corresponds to rows of the variable var. In addition, the array must implement both a vertcat method and a size method with a dim argument."
