I want to have a table with three columns. The first column have a long text and the others have short. I am using below code:
but the text in first column cannot be seen well and the other columns disappeared as in the figure. Please help me. Thanks

tabcolsep=0.11cm

begin{table*}

    newcommand{tabincell}[2]{begin{tabular}{@{}#1@{}}#2end{tabular}}

    caption{SegNet Performance with Different Optimizers.}



    centering

    begin{tabular}{|c|c|c|}hline

        tabincell{c}{Text Message} & tabincell{c}{Video Number} & tabincell{c}{State}\hline

        part of the Semantic feature have proved to be a very good

        feature if the little effort in making paraphrases in the corpus

        can be done. & tabincell{c}{74} & tabincell{c}{craving}\hline

        Computer Science is a specialized domain, and so any or-

        dinary paraphrases generation cannot be easily used here

        unless there is a human effort be involving in marking the

        words that can be permuted from the original to form true or

accurate paraphrases & tabincell{c}{0.8219} & tabincell{c}{0.8014} \hline

    end{tabular}

vspace{0.25 cm}

label{tab2.Spec}

end{table*}

Use tabularx and set the first column header to X.

Here's a solution which (a) is very similar to the one given in @AboAmmar's answer, in that it uses a tabularx environment and the X column type for the first column, and (b) gives the table a more open "look" by omitting all vertical rules and employing fewer, but well-spaced, horizontal rules.

Note that all tabincell "wrapper" directives may be omitted.

usepackage{tabularx,booktabs}

usepackage[skip=0.333baselineskip]{caption} % optional

begin{table*}

%tabcolsep=0.11cm  % is this really needed?

caption{SegNet Performance with Different Optimizers.}

Part of the Semantic feature have proved to be a very good feature if the little effort in making paraphrases in the corpus can be done.

Computer Science is a specialized domain, and so any ordinary paraphrases generation cannot be easily used here unless there is a human effort be involving in marking the words that can be permuted from the original to form true or accurate paraphrases.
