# width

Number of table variables

## Syntax

``W = width(T)``

## Description

example

````W = width(T)` returns the number of variables in table `T`.`width(T)` is equivalent to `size(T,2)`.```

## Examples

collapse all

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.
