{#- This is a Jinja template - Flask uses Jinja as its templating engine. Jinja
will process this file looking for directives to define a template based on
the passed-in variables. This template relies on the `table`, `header`, and
`username` variables to be declared.
A Jinja directive will start with a "{%" and Jinja comments will begin with
a "{#". Both are ended with the same symbol and the closing brace "}".
If a dash "-" is provided before the opening or closing symbol for a
directive, Jinja will ignore all whitespace up to that side of the directive
in the template. -#}
