[Tex/LaTex] Align subcaption to its subtable

horizontal alignmentsubcaptionsubfloats

I am trying to create a table with tree subtables in it. To do so I have written the following code:

\documentclass[twoside]{article} 
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{sidecap}
\usepackage{fancyhdr}
\usepackage{lastpage}
\usepackage{extramarks}
\usepackage{graphicx}
\usepackage{mathpazo}
\usepackage{amsmath}
\usepackage{float}
\usepackage{wrapfig}
\usepackage{multicol}
\usepackage[toc,page]{appendix}
\usepackage{subcaption}

\begin{document} % <---
\begin{table}[h]
\begin{subtable}[b]{0.5\textwidth}
\centering
\begin{tabular}{ll|ll}
\multicolumn{2}{c|}{Consumo} & \multicolumn{2}{c}{Producción} \\ \hline
Metabolito      & Valor      & Metabolito       & Valor       \\ \hline
D-Fructosa      & 10,00      & CO\textsubscript{2}              & 22,81               
\\
Amonio          & 4,77       & H\textsubscript{2}O              & 29,18           
\\
Fosfato         & 3,21       & H\textsuperscript{+}               & 17,53       
\\
O\textsubscript{2}              & 22,00      & Acetato          & 0,0038      \\ \hline
\end{tabular}
\caption{\textit{E.coli} con fuente de carbono fructosa}\label{tabla4.1}
\end{subtable}
\begin{subtable}[b]{0.5\textwidth}
\centering
\begin{tabular}{ll|ll}

\end{tabular}
\caption{\textit{E.coli} con fuente de carbono fructosa}\label{tabla4.2}
\end{subtable}
\begin{subtable}[]{0.5\textwidth}
\vspace{15pt}\hspace{0.5\linewidth}\begin{tabular}{ll|ll}
\multicolumn{2}{c|}{Consumo} & \multicolumn{2}{c}{Producción} \\ \hline

Fosfato         & 3,21       & H\textsuperscript{+}               & 17,53       \\
O\textsubscript{2}              & 22,00      & Acetato          & 0,0038      \\ \hline
\end{tabular} \caption{\textit{E.coli} con fuente de carbono fructosa}\label{tabla4.3}
\end{subtable}
\caption{Resultados de las distintas simulaciones}
\end{table}
\end{document}% <---

The problem is that the third subtable is not aligned with its caption:

Is there any easy solution to align them?

your tables are wider than width of \subtable, consequently using your mwe (after adding missing parts of code, see my comment above) your tables overlaps (red lines on image below indicate your page layout):

considering my suggestion in comment above, you will obtain:

if i increase text width with use of the package geometry (using its default page layout settings) than i obtain after some small tweak of your subtable size, i obtain:

Edit: code, where is for chemical formulas used the mhchem package, for the last case is:

[Tex/LaTex] threeparttable not working with subcaption(subtable), error: table inside subtable

The problem is that the caption package redefines the threeparttable environment to set the caption type to table. caption uses the caption type to check for inappropriate nesting. In this case, it therefore finds an attempt to set caption type to table when it is within the subtable environment. It knows that isn't allowed, so it gives an error.

The simplest solution, especially if some of your threeparttables are not of type subtable, is to use the fact that it works if you put the subtable inside the threeparttable. Alternatively, you can just set the caption type within the threeparttable environment rather than using the subtable environment at all.

However, as your update points out, this sadly restarts the counter for each sub-table. Here is a solution which avoids this difficulty.

Note that the idea here is that you could change the options for threepartsubtable specifically, just as you could change them for threeparttable. I think there must be a way to do this more elegantly, but have not yet found one.

That is, I have precious little clue ...

Caveat emptor.
