Problem for adding accordion

I have added three rows. First is the photo slider, second is a table (using visual editor) and third part is a accordion(using visual editor). However, there is a big space gap between the second and third row. No such happened between the first and second row. I have checked the HTML codes to find that there is a break shown as below.

jQuery UI Accordion – Collapse content

$(function() {
$( “#accordion” ).accordion({
heightStyle: “content”
});
});

Would you please help to advise how can I remove this big gap.

Thanks.
