Trim is to judge whether to retain the output value of the front and back blank characters, the default false, that is to say, output all characters.
The following 2 output methods, one default trim="false", the other trim="true".
As you can see, the first method outputs as it is, including front and back spaces and newline characters, while the other removes spaces and newline characters.
The separator between the loop output. If a delimiter is specified, the output elements are separated by separator.
