The following error out when adding to a <table>

$('table').append('<caption>');
$('table').append('<caption></caption>');
$('table').prepend('<caption>');
$('table').prepend('<caption></caption>');

Nothing happens to the following when adding to a <table> and returns an empty object

$('<caption>').appendTo('table')
$('<caption>').prependTo('table')

The following adds ONLY the word "Test" when adding to a <table>

$('table').append('<caption>Test</caption>');
$('table').prepend('<caption>Test</caption>');
$('<caption>Test</caption>').appendTo('table');
$('<caption>Test</caption>').prependTo('table');
