• Please extend your code fragment to complete small document (MWE: Minimal Working Example) which we can test as it is. BTW, inserting your table in an article document, I can0t reproduce your problem )looking in Sumatra). From code can be concluded, that your problem is pdf viewer artifact, Jun 8 at 20:00

As I mentioned in my comment, first vertical line in table is present, but apparently in your pdf viewer is not visible. If you will zoom beginning of table, it will become visible also in it.

Off topic: I would write your table differently. For table I would use tabularray package and for list in cells enumitem package. Using them table's code become concise and clearer. With use of \small font size are text better accommodate to cells sizes.

Addendum (1): As suggest @Mico in his comment, using leftmargin=* for list formatting is for many people more appealing as is shown in above solution. Also bullets is (for many= nice than used dash With thicker lines may make lines better visible also in colored columns/cells:

• You use document class which is not public, so its structure is unknown as well its combability with packages.
• many packages are loaded twice or more since some of them are already loaded by other packages.
• It is unknow, if you really need all these packages. Some are obsolete (epsfig) some have loaded their supersedes (amsmath --> mathtools, colortbl-->[table, ...]{xcolor}˙

I suggest to remove all duplicate and grouping packages according to their purpose, for example for math, tables etc.), then test if all packages are really needed (comment one after one and see if document still can be compiled).

Since I haven't used document classes and some of loaded packages, I can't test table with your document.

• +1. I would probably use the option left (or leftmargin=*) rather than wide, though.

– user258528
Jun 8 at 22:11
• @Nasser, I'm sorry. Since you are on Overleaf, I can't help you much (I0m not familiar with it, I'm only informed, that it use version from June las year, after then due to fast development of package was seven releases till now. So you must usk their support how you can install it in your folder recent version of package) Other possibilities, that you install some Latex distribution (MiKTeX, TeXlive, etc., depends on OS which you use). Otherwise is better to stick with nice Mico answer and ask them for eventual changes which you like to do on suggested code. Jun 9 at 0:02

As @Zarko has already pointed out in a comment, the "disappearing lines" issue you've encountered is a browser-issue artifact. Since the gray columns and rows don't do much anyway, aesthetically speaking, you might was well omit the gray stuff. I'd rather focus on simplifying the inputs by getting rid of all the tabular "wrappers" and letting LaTeX do most of the formatting job, mainly by setting up bespoke itemize-like environments in columns 2 and 3.

In the following, I've used an xltabular environment, which combines the capabilities of longtable and tabularx environments, instead of the longtable environment.

• Do I need to copy whole code above?

• @Nasser - Well, as the screenshot I posted attests, my code DOES WORK. Please clarify what you did in the process of “copying my code”. E.g., did you copy the preamble material as well as the body of the document? Or maybe just the body but not the preamble? Please be specific.

• @Nasser - You mentioned that you copied the code between \begin{document} and \end{document} into the body of your document. I take it that this means that you did not copy the preamble material into the preamble of your document. That would certainly explain why you can't compile my code. You needn't copy the first three lines (the \documentclass declaration and the first two \usepackage statements), but you should definitely copy over the rest.

• @Nasser - My TeX distribution does not appear to feature any files related to the uddissert2021` document class. Hence, I cannot compile your code. Sorry.

• Off-Topic: Among many things I like about this website, other than the highly skilled latex users and useful answers, is also the beautiful patience, decent and respectful replies from people like Mico. Thank You! Jun 9 at 1:05
