• that table generator comes up here from time to time but why use it? It makes massively over-complicated tex (you could remove all those \multicolum{{1}{... commands) It would be simpler to write the tex code directly. – David Carlisle Nov 8 at 13:22

Nope --could not find any error--had to reduce one column to 8cm to avoid spill over

Something like the following?

Note that I've deliberately dropped all vertical lines and almost all horizontal lines, in order to give the table a more open and inviting look. After all, what purpose is served if the table is so uninviting that none of your readers will spend more than two seconds glancing at it? Input-wise, I've also replaced all instances of {[}Hz{]}} with Hz, and I've switched from a tabular to a tabularx environment. A side effect of these simplifications is that the multitude of utterly pointless \multicolumn{1}{|l|}{} directives can be deleted, making the input much easier to take in -- and check for any errors of content.

Your table code does not reproduce showed error. However, I would redesign your table to something like this:

IN your table code i would remove all \multicolumn{1}{...}{...} which is only clutter in code. Also I would remove vertical lines (combination of the rules from booktabs package and vertical lines gives ugly result). Text in last columns sre to long that table can be fit in text area. A solution is to use column type which break test into more lines. For this I suggest to use tabularx and X column type. For writing units is intended excellent package siunitx which support their writing according to SI standard:

\documentclass{article}
\usepackage{booktabs, makecell, multirow, tabularx}
\setcellgapes{3pt}
\usepackage{siunitx}

\begin{document}
\begin{table}[ht]
\setlength\tabcolsep{4pt}

\begin{tabularx}{\linewidth}{@{} ll>{\raggedright\arraybackslash}X@{} }
\toprule
U   & Frequee   & Descn                     \\
\midrule
\multirow{8}{*}{interaction}
&   \SIrange{1}{2}{\hertz}
&   The maximum bandwidth with which the human finger can react to unexpected force/position signals              \\
%    \cmidrule(l){2-3}
& \SIrange{5}{10}{\hertz}   &   vvvv    \\
%    \cmidrule(l){2-3}
& \SIrange{8}{10}{\hertz}   &   vvvv    \\
%    \cmidrule(l){2-3}
& \SIrange{8}{10}{\hertz}   &  vvces    \\
\midrule
section
& \SIrange{12}{16}{\hertz}  &   The  cannot correct ps  \\
\midrule
\multirow{5}{*}{interaction}
& \SIrange{12}{30}{\hertz}  &  The which the human finger demans taperception \\ %    \cmidrule(l){2-3}
& \SI{320}{\hertz}          &  The yond which the human fingers cannot discrimins\\
%    \cmidrule(l){2-3}
& \SIrange{5}{10}{\hertz}   &  The human finger needs to sense vibratitive tasks\\ \bottomrule
\end{tabularx}
\end{table}

Addendum: I test my solution with your document preamble. It gives warnings (not error) that used package scrpage2 should be replaced with scrlayer-scrpage. Doing this and moving the hyperref package to the end of preamble and consider, that in your document you change \baselinestretch, the new version of mine MWE is:

Compiling it with recent version of the MikTeX I got no errors and four warnings:

• LaTeX Warning: Command \InputIfFileExists has changed.
• Package scrlayer-scrpage Warning: Command deprecated!
• Package scrbase Warning: \ifpdftex was redefined
• Package scrbase Warning: \ifVTeX was redefined

Warnings not harm result of compilation. Note, this warnings you obtain also without table proposed solution for your table. MWE gives:

• Thank you very much. I am adding the packages of multirow etc. I am getting the following error: – maths Nov 8 at 13:45
• scrpage2.sty 52 Package scrpage2 Warning: usage of obsolete package! Package scrpage2' is obsolete. You should not longer use package scrpage2'. You should replace usage of package scrpage2' by scrlayer-scrpage' on input line 52. – maths Nov 8 at 13:46
• @maths, as I said. Error is not in your table code, but as you now discover yourself in use of the obsolete package. Replace it with suggested one. Anyway, code for table in my answer is significantly cleanup from clutter in your code. – Zarko Nov 8 at 13:51
• @maths - You report that the macro \setcellgapes is undefined. Did you maybe fail to load the makecell package? – Mico Nov 8 at 14:38
