I am using document class elsarticle. In a table I want to break lines in multiple lines while keeping it two col format

Question

Here what I am using

  \begin{table}[h]
        \resizebox{\columnwidth}{!}{%
        
    \begin{tabular}{c c c c}
        
        
        \hline
        Dataset&Number of Speakers& Total utterances&Emotions\\
        \hline
        Berline Emotional Speech Database&10(5M,5F)&535&Angry, Boredom, Disgust, Fear, Happy, Sadness, Neutral\\
        
        
        
    \end{tabular}
}
\end{table}

And the output is

But I want this

please guide.

After Mico's answer, I am getting this. Just need to add separation between these three items without adding any extra col for serial number. Also How to increase the width of the first and last col? Actually I need to understand this whole line\begin{tabularx}{\textwidth}{@{} *{3}{C{0.8}} C{1.6} @{}} Here what I am guessing : 3 means first 3 col widths of 0.8 and last of 1.6? plz, guide. regards

Answer 1

Remark: I wrote this answer to address the OP's initial query. Some time after I posted this answer, the OP changed the query more or less completely. I'm afraid that, as a result, my answer has become pretty much unintelligible to future readers, since it continues to address a query which is now no longer there.

I'd like to suggest that you employ a tabularx environments, with four centered versions of the X column type, and set the overall width to \columnwidth.

Alternatively, you could let the table occupy the width of both columns by using a table* environment and setting the width of the tabularx environment equal to \textwidth.

\documentclass[twocolumn]{elsarticle}
\usepackage{tabularx,ragged2e,booktabs}
\newcolumntype{C}[1]{>{\Centering\hsize=#1\hsize}X}
\begin{document}
\begin{table}[h] % all columns have same width
\begin{tabularx}{\columnwidth}{@{} *{4}{C{1}} @{}}
        \toprule
        Dataset & Number of speakers & Total utterances & Emotions\\
        \midrule
        Berlin Emotional Speech Database & 10 (5M,~5F) & 535 & Angry, Boredom, Disgust, Fear, Happy, Sadness, Neutral\\
        \bottomrule
\end{tabularx}
\end{table}

\begin{table*}[h] % final column is twice as wide as first three
\begin{tabularx}{\textwidth}{@{} *{3}{C{0.8}} C{1.6} @{}}
    \toprule
    Dataset & Number of speakers & Total utterances & Emotions\\
    \midrule
    Berlin Emotional Speech Database & 10 (5M,~5F) & 535 & Angry, Boredom, Disgust, Fear, Happy, Sadness, Neutral\\
    \bottomrule
\end{tabularx}
\end{table*}

\end{document}

Addendum to address one of the OP's follow-up queries:

I need to understand this whole line \begin{tabularx}{\textwidth}{@{} *{3}{C{0.8}} C{1.6} @{}}

Let's start with the definition of the C column type:

\newcolumntype{C}[1]{>{\Centering\hsize=#1\hsize}X}

Here, the X column type is defined by the tabularx package and \Centering is a macro defined by the ragged2e package. If one or more columns of type X are present, their width is calculated as a residual, i.e., after subtracting the widths of all other columns from the first argument of the \tabularx environment. For instance,

\begin{tabularx}{\columnwidth}{@{} *{4}{C{1}} @{}}

means that the overall width (the first arg. of the tabularx environment) is equal to \columnwidth, while *{4}{C{1}} means "4 columns of type C, all equally wide". (The @{} particles serve to suppress whitespace padding at the edges of the table.) The argument of C is a relative width, where "relative" is in reference to the case of equal-width X-type columns. The main rule to follow here is that sum of the relative column widths (here: 1+1+1+1=4) must be equal to the number of X-type columns (here: 4).

We may now turn to the second tabularx environment:

\begin{tabularx}{\textwidth}{@{} *{3}{C{0.8}} C{1.6} @{}}

Its overall width is \textwidth (which is more than twice as large as \columnwidth, and it consists of 4 columns overall. The first three are centered X-type columns with relative widths equal to 0.8, while the fourth is also a centered X-type column, with relative width of 1.6. Observe that 3*0.8+1.6 = 2.4+1.6 = 4 = number of X-type columns. In words: the usable width of the final column is twice that of the usable width of the first three columns." If you want to increase the relative widths of the first and last columns, you must also decrease the relative width of the second and third columns. E.g.,

\begin{tabularx}{\textwidth}{@{} C{0.9} C{0.7} C{0.7} C{1.7} @{}}

would be a syntactically correct specification.
