spacing between chapters in list of tables

Question

tocloft seems to automatically add extra space between table entries from different chapters. I want a single space between all the entries in the list of tables. Right now I have one space between entries from the same chapter and two spaces between those from different chapters. Here's a MWE of what I have.

\documentclass[11pt, letterpaper]{thesis}

\usepackage[lmargin=1.5in, rmargin=1.0in, tmargin=2.0in, bmargin=1.0in]{geometry}


\renewcommand{\thechapter}{\Roman{chapter}}
\renewcommand{\thesection}{\arabic{section}}
\renewcommand{\thetable}{\arabic{chapter}.\arabic{table}} 

\usepackage{tocloft}
\addtocontents{lot}{Table \hfill\ {Page} \par}

\usepackage{titlesec}
\usepackage{caption}
\usepackage{ctable}
\usepackage{tabularx}


\begin{document}


% List of Tables

\renewcommand{\cftlottitlefont}{\normalfont}
\renewcommand\listtablename{\centerline{TABLES}}
\renewcommand{\cfttabaftersnum}{.}
\setlength{\cfttabindent}{0pt}
\setlength\cftbeforechapskip{0pt}
\setlength\cftbeforetabskip{11pt}

\listoftables

% End List of Tables


\chapter{Chapter One}

\begin{table}[htbp] 
  \centering
    \begin{tabular}{lll}
    \toprule
    & Col 1 & Col 2 \\
    \midrule
    Row 1 & 11 & 12 \\
    Row 2 & 21 & 22 \\
    \bottomrule
    \end{tabular}
  \caption{This is table 1.1.}

    \end{tabular}
  \caption{This is table 1.2.}
\end{table}

    Row 2 & 21 & 22 \\
    \bottomrule
    \end{tabular}
  \caption{This is table 2.1.}
\end{table}

\begin{table}[htbp]

    \bottomrule
    \end{tabular}
  \caption{This is table 2.2.}
\end{table}

\end{document}

I use \setlength\cftbeforechapskip{0pt}, but this seems to have no effect. I did find this: How to change the line spacing in my list of figures? and tried some of the suggestions but none seemed to work for me. Any ideas?

Answer 1

That space is not produced by tocloft but by the class used, usually in the definition of \@chapter (at least in the standard classes); one possible solution would be to redefine this command to suppress the additional spacing; the code below shows this redefinition for the standard class book (the lines adding space to the LoF and LoT were commented out and marked with %NEW):

Since you are usinga non-standard class, the above silution might not be appropriate for you; in that case, we will need to see how your class is adding this space.
