I use, in agreement with the post of SE, the command link.

documentclass[10pt]{article}

usepackage{bookmark}

usepackage[table]{xcolor}

usepackage{tabularx}



newcommand{link}[1]{%

    {%

        deftextbf##1{##1}%

        deftextit##1{##1}%

        deftextcolor##1##2{##2}%

        defprotect##1##2{##2}%

        edef_{string_}%

        edef&{string&}%

        xdeftmp{noexpandhref{#1}}}%

    ttfamily%

    tmp{#1}%

}



begin{document}



    begin{tabularx}{linewidth}{|l|l|}

        link{https://www.textcolor{blue}{longlink}.com/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/longlink/} & Long link descriptiontabularnewline

        link{www.textcolor{blue}{longlinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglinklonglink}.net} & Long link descriptiontabularnewline

    end{tabularx}



end{document}

and I get:

So… two questions:

• How can I change the text of link to get the hyphenation on the slash character without the hyphen char?

and if there isn't any slash character

• How can I change the text of link to get hyphenation anywhere but without the hyphen char?

The idea is the same, but using more powerful expl3 methods.

With link{<link>} you get the same as before, but with the possibility of breaking lines at slashes.

With link*{<link>} you allow breaking at any letter. However this requires changing textcolor{blue}{<string>} to blue{<string>} otherwise also blue would be considered for breaking. Define similar commands for all colors you need and update the equivalences.

It is also possible to adopt the “break everywhere” strategy when there is no slash:
