Create a well-formatted table in LaTeX

Question

I'm trying to add a unique table displaying the regression results in my working paper. However, I'm facing three issues: i) I'm unable to insert "Dependent Variable: y$_{it}" as a caption just above the table.

ii) I'm struggling to include the legend regarding the p-values and the text "In this table, we present the average marginal effects, with robust standard errors displayed within parentheses. All the regression models include a full set of year dummies" just below the table.

iii) The table is too wide and needs to be adjusted to fit on the sheet.

My attempt as follows

\documentclass[12pt,fleqn,a4paper]{article}
\usepackage{caption}
\usepackage{booktabs}
\usepackage{array}
\usepackage{amsmath}



\begin{document}



\begin{table}[htbp]
    \centering
    \caption{%
        Dependent Variable: y$_{it}$
    }
    \vspace{0.5em} 
    \begin{tabular}{ccccccc}
        \toprule
        \textbf{Variable} & \textbf{Model 1} & \textbf{Model 2} & \textbf{Model 3} & \textbf{Model 4} & \textbf{Model 5} & \textbf{Model 6}  \\
        \midrule
        k$_{it}$ & & & & & &    \\
        & & & & & & \\
        h$_{it}$ & & & & & &\\
        & & & & & & \\
        Americas & & & & & &\\
        & & & & & & \\
        East Asia and South Asia and Pacific & & & & & &       \\
        & & & & & &  \\
        Europe and Central Asia & & & & & & \\
        Middle East and  North Africa & & & & & &       \\
        & & & & & &  \\
        \midrule
        Sample  & & & & & &  \\
        N       & & & & & &\\
        McFaddenR$^{2}$     & & & & & & \\
        \bottomrule
        \addlinespace[1ex]
        \multicolumn{4}{l}{\textsuperscript{***}$p<0.01$, \textsuperscript{**}$p<0.05$, \textsuperscript{*}$p<0.1$. In this table, we present the average marginal effects, with robust standard errors displayed within parentheses. All the regression models include a full set of year dummies.}
        \label{probit1}
    \end{tabular}
\end{table}

\end{document}

Answer 1

To have a table with three parts (caption, table, and notes), the better option is to use the package threeparttable.

The c columns center text in one line, so you have a very big table that does not fit.

Find below a try at it, but probably this table must be re-thought; read the suggestions here.

I used the threeparttable package, changed the first column to a p{}\ (paragraph) one (with ragged-right text), and reduced the size of the font to \footnotesize. Still, it doesn't fit the standard article width by almost 30 pt... (so it's not correctly centered on the page).

\documentclass[12pt,fleqn,a4paper]{article}
\usepackage{caption}
\usepackage{booktabs}
\usepackage{array}
\usepackage{amsmath}
\usepackage{threeparttable}
\usepackage{ragged2e}

\begin{document}
\begin{table}[htbp]
    \footnotesize
    \begin{threeparttable}[b]
        \caption{%
            Dependent Variable: $\mathrm{y}_{it}$
        }
        \label{probit1}
        \begin{tabular}{>{\RaggedRight}p{3cm}cccccc}
            \toprule
            \textbf{Variable} & \textbf{Model 1} & \textbf{Model 2} & \textbf{Model 3} & \textbf{Model 4} & \textbf{Model 5} & \textbf{Model 6}  \\
            \midrule
            $\mathrm{k}_{it}$ & & & & & &    \\
                     & & & & & & \\
            $\mathrm{h}_{it}$ & & & & & &\\
                     & & & & & & \\
            Americas & & & & & &\\
                     & & & & & & \\
            East Asia and South Asia and Pacific & & & & & &       \\
                                                 & & & & & &  \\
            Europe and Central Asia & & & & & & \\
                                    & & & & & &  \\
            Middle East and  North Africa & & & & & &       \\
                                          & & & & & &  \\
            \midrule
            Sample  & & & & & &  \\
            N       & & & & & &\\
            McFaddenR$^{2}$     & & & & & & \\
            \bottomrule
        \end{tabular}
        \begin{tablenotes}
            \item [] \textsuperscript{***}$p<0.01$, \textsuperscript{**}$p<0.05$, \textsuperscript{*}$p<0.1$. In this table, we present the average marginal effects, with robust standard errors displayed within parentheses. All the regression models include a full set of year dummies.
        \end{tablenotes}
    \end{threeparttable}
\end{table}
