I want to add an additional column to the list of symbols for inserting the belonging units to the preceding variables.

In my case, it is necessary to use three different and independent glossary-lists (acronymslist, symbolslist and glossary) like shown below. However, the third column should be used only in the symbolslist.

Minimum Working Example (MWE):

documentclass{scrbook}                           % documentclass: scrbook

usepackage[acronym,toc]{glossaries}              % use glossaries-package



newglossary[slg]{symbolslist}{syi}{syg}{Symbolslist} % create add. symbolslist

makeglossaries                                   % activate glossaries-package





% ==== EXEMPLARY ENTRY FOR SYMBOLS LIST =========================================

    newglossaryentry{symb:Pi}{name=ensuremath{pi},

        description={Geometrical value},

        type=symbolslist}





% ==== EXEMPLARY ENTRY FOR ACRONYMS LIST ========================================

    newacronym{VRBD}{VRBD}{Violet-Red-Bile-Glucose-Agar}





% ==== EXEMPLARY ENTRY FOR MAIN GLOSSARY ========================================

    newglossaryentry{Biofouling}{name=Biofouling,description={Some description}}





begin{document}



    glsaddall



    printglossary[type=acronymtype,style=long]  % list of acronyms

    printglossary[type=symbolslist,style=long]   % list of symbols

    printglossary[type=main]                     % main glossary



end{document}

Screenshot of the result:

As expected, this MWE creates three different types of lists what is entirely correct. Now, I want to add a third column only to the list of symbols for inserting the units. It would be great if we can create something beautiful like the following table-layout.

Screenshot of the final (desired) state:

I have borrowed this shapely layout from this topic. Unfortunately, the belonging MWE doesn't work together with scrbook-class. Is there any other possibility to expand my own code from the top to generate such a layout (including the hrule)?

Thank you very much for your help!

I suggest to use a separate unit key for the symbol unit and refer to it with glsunit. (Alternative: Use the user1...user6 keys for this feature)

In addition, this key must be used in the glossarystyle. I've defined a new style based on the already provided long3col style which displays the symbols in the requested order.

documentclass{book}                           

usepackage{siunitx}

usepackage[acronym,toc]{glossaries}              % use glossaries-package





setlength{glsdescwidth}{15cm}



newglossary[slg]{symbolslist}{syi}{syg}{Symbolslist} % create add. symbolslist





glsaddkey{unit}{glsentrytext{glslabel}}{glsentryunit}{GLsentryunit}{glsunit}{Glsunit}{GLSunit}



makeglossaries                                   % activate glossaries-package

Just adding to Christian's answer: to use the unit macros inside the si{unit} command defined by siunitx such as metre and kilowatt used in his MWE, one should add the command glssetnoexpandfield{unit} before setting any entries.

It is better explained in This Answer.
