# Two tables side by side with independent and global captions

I want to put two tables side by side in my document, with (a) and (b) subcaptions for them, and also a global caption "Table 1. Blahblahblah" (spanning to one of the columns only). At the moment I am only able to put the tables with independent captions (as seen in the image below). I've tried the subcaption package and subtable but it claims that subtable environment was undefined. I've also tried the subfigure package but it clashes with the subfig package.



What I currently get:

I want something like this below but adding (a) and (b) subcaptions:

Thank you

It works with either subcaption:

or with floatrow (which makes it easy to have side captions):

I supposed you wanted the row of subtables to be display across both columns. Here's the code, which I commented for the floatrow version:

\documentclass[conference]{IEEEtran}
\thispagestyle{plain} % To force page numbering when using conference IEEEtran

\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\newcommand{\subfigureautorefname}{\figureautorefname} % For autoref to name subfloats as Figure
\renewcommand{\tablename}{Table}

%%%%%%%%%% FIGURES %%%%%%%%%%%
\usepackage[justification=centering]{caption} % Figures caption
\usepackage{graphicx}
\captionsetup{labelsep = period} % Figure 2. Caption (rather than Figure 2: Caption)
%\usepackage{float} % To place figures where I want with [H]
\renewcommand{\figurename}{Fig.} % Fig.2 (rather than Figure 2)
\usepackage{caption, subcaption, floatrow}
