-## The `@dissallowna` command
+## The `@disallowna` command
 
-The `@dissallowna` command has the form `source |> @dissallowna(columns...)`. `source` can be any source that can be queried and that has a table structure. If `@dissallowna()` is called without any arguments, it will check that there are no missing `NA` values in any column in any row of the input table and convert the element type of each column to one that cannot hold missing values. Alternatively one can pass a list of column names to `@dissallowna`, in which case it will only check for `NA` values in those columns, and only convert those columns to a type that cannot hold missing values.

-Our first example uses the simple version of `@dissallowna()` that makes sure there are no missing values anywhere in the table. Note how the column type for column `a` is changed to `Int64` in this example, i.e. an element type that does not support missing values:
