How remove dot after section number in ToC with babel's spanish?

Question

I'm using the book document class and the babel package with the spanish option, I have a ToC like this:

1. CHAPTER NAME
   1.1. SECTION NAME
   1.1.1. Subsection name
   1.1.1.1. Subsubsection name

How can I remove the dot after sections numbers, tables numbers on LoT and figure numbers on LoF?.

P.S.: The Chapter number should have a dot.

Here a MWE

\documentclass{book}
\usepackage[spanish,es-lcroman]{babel}

\setcounter{secnumdepth}{4}
\setcounter{tocdepth}{4}
\makeatletter
\def\@seccntformat#1{\csname the#1\endcsname\quad}
\makeatother

\begin{document}

\tableofcontents

\listoftables

\listoffigures

\chapter{CHAPTER NAME}

\section{SECTION NAME}

\subsection{Subsection name}

\subsubsection{Subsubsection name}

\begin{table}
    My table
    \caption{Table}
\end{table}

\begin{figure}
    My figure
    \caption{Figure}
\end{figure}

\end{document}

Note that I'm using the code:

\makeatletter
\def\@seccntformat#1{\csname the#1\endcsname\quad}
\makeatother

to remove the dot after sections number in the document.

Answer 1

The Spanish module for babel is responsible for this, probably following some directive of the authority on the language. There is an additional option for disabling it:

\usepackage[spanish,es-lcroman,es-nosectiondot]{babel}

See section 2.3 in the documentation for the Spanish option (texdoc spanish or here on TeXdoc.net).

There will be no need to act on \@seccntformat.

In order to keep the period after the chapter number (although I don't see why), patch the \@chapter command:

\usepackage{etoolbox}
\makeatletter
\patchcmd\@chapter{\numberline{\thechapter}}{\numberline{\thechapter.}}{}{}
\makeatother
