Space between table and caption in Beamer

Question

I am making a slide using Stockton beamer theme.

I have added a table to a frame, however as you can see in the screenshot, that space between caption and table is too much. I made some search and found these codes,

\usepackage{subfig}
\captionsetup[table]{belowskip=1pt,aboveskip=1pt}

\usepackage[font=small,skip=0pt]{caption}

However, they both are not working. How can I solve this problem? Table looks so bad in this slide.

\documentclass[xcolor=svgnames]{beamer} 
\usetheme{Stockton}

\usepackage{epsfig} %for figures
\usepackage{xcolor} %for color

\definecolor{hughesblue}{rgb}{.9,.9,1} %A blue I like to use for highlighting, matches Hughes Hallet's book

\logo{\includegraphics[height=2cm]{Seal_Cream.pdf}} % comment out this line if you do not have the pacific-seal file}

Answer 1

belowskip=0pt of caption package seems to do the job. Also, the table environment is adding whitespace between text and the table. You can use \captionof command instead.
