I just came across this ! (backslash exclamation mark) in the code for a table in somebody else's tex and I was wondering what it does.
begintable[hbt]
centering
resizeboxcolumnwidth!%
setlengthextrarowheight1pt
begintabularl
toprule
textbfThing & $a$ & $b$ & $c$ & $d$ & $e$\
midrule
Stuff & !!100!! & !!$10^6$!! & !!$pi_0$!! & $sigma$ & $2^30$\
bottomrule
endtabular%
endtable
My tex editor says unrecognized command but it compiles just fine.
I've tried on overleaf and it seems to tighten the table somehow. Does anybody know more?

A!is a negative space, see tex.stackexchange.com/questions/9091/… for more information.

I don't know what the commands ! are supposed to do in the code you show, other than raising many errors.
The command ! is only allowed in math mode (unless redefined, which I'd discourage). It's purpose is to insert a negative thin space, which is useful in several places. For instance
biggl(frac12112-1biggr)^!2
is an improvement over ^2, because it moves the exponent towards the parenthesis and takes care of its bending.
Another place where it is helpful is in 2/!log x, because for technical reasons / is an ordinary symbol and TeX would add a thin space between it and the “log†operator.
Here's a picture: left the output with !, right without.
If you want to tighten a table, reduce the size of tabcolsep. Using explicit negative spaces all over the place is not the correct way.
And never use resizebox on a table.

This symbol is usually defined as
! negative thin space (normally 1/6 of a quad)
It is commonly used in tables, and formulas among other ways to manipulate spaces in LaTeX
And before you do post a question, please do run a search with similar keywords on this site. Hope this helps.

@daleif I am not sure if I can provide examples that are relevant here, since it is a matter of usage, and remember coming across it in tables.
