Create a table, T. 

LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];

T = table(Age,Height,Weight,BloodPressure,'RowNames',LastName)
T=5×4 table
                Age    Height    Weight    BloodPressure
                ___    ______    ______    _____________

    Smith       38       71       176       124     93  
    Johnson     43       69       163       109     77  
    Williams    38       64       131       125     83  
    Jones       40       67       133       117     75  
    Brown       49       64       119       122     80

Find the number of variables in table T. 

W = width(T)
W = 4

T contains 4 variables; width does not count the row names.

The variable BloodPressure counts as one variable even though it contains two columns.

Input Arguments

collapse all

Input table, specified as a table.

Variables in a table can have multiple columns, but width(T) only counts the number of variables.
