TeX - LaTeX Asked by LukeTheWolf on April 7, 2021
I’m pretty new to Latex, and I would like to copy in my notes this "table".
I have initially created a table, but, the result wasn’t as good as the picture.
Can somebody help me to translate this image in Latex?
Thanks in advice!
This is what I’ve done so far:
begin{center}
begin{tabular}{ |c|c| }
hline
multirow{2}{*}{Leggi Associative} & $E cup F = F cup E$
& $E cap F = F cap E$
hline
multirow{2}{*}{Leggi } & $(E cup F) cup G = E cup (F cup G)$
& $(E cap F) cap G = E cap (F cap G)$
hline
multirow{2}{*}{Leggi Distributive} & $E cup (F cap G) = (E cup F) cap (E cup G)$
& $E cap (F cup G) = (E cap F) cup (E cap G)$
hline
multirow{2}{*}{Leggi di De Morgan} & $(E cup F)^c = E^c cap F^c$
& $(E cap F)^c = E^c cup F^c$
hline
end{tabular}
end{center}
You should consider that some of the picture’s laws have not been written yet
I believe that the proposed typesetting is ugly because very unbalanced.
There is no reason for right aligning the labels, nor for moving them midway between the formulas (as you tried to do with multirow
).
There's no reason for aligning the equals signs, which are completely unrelated with each other (when in different groups).
A one time hack is needed for the last set of laws.

usepackage{array,booktabs}
begin{document}
begin{center}
% hack to get the alignment
defvemptyset{ooalign{hfil$emptyset$hfilcrphantom{$Omega$}cr}}
begin{tabular}{ @{} ll @{} }
toprule
Leggi associative & $E cup F = F cup E$
& $E cap F = F cap E$
addlinespace
Leggi di assorbimento & $(E cup F) cup G = E cup (F cup G)$
& $(E cap F) cap G = E cap (F cap G)$
addlinespace
Leggi distributive & $E cup (F cap G) = (E cup F) cap (E cup G)$
& $E cap (F cup G) = (E cap F) cup (E cap G)$
addlinespace
Leggi di De Morgan & $(E cup F)^c = E^c cap F^c$
& $(E cap F)^c = E^c cup F^c$
addlinespace
Leggi di identità & $Ecupvemptyset=E$
& $EcapOmega=E$
bottomrule
end{tabular}
end{center}
end{document}
Depending on the context, you may want to remove the rules above and below. Capitalization is not used in Italian.
The hack can be realized in different ways.

documentclass{article}
usepackage{amsmath}
begin{document}
begin{alignat*}{2}
text{Leggi Commutative} & qquad & E cup F &= F cup E
& & E cap F &= F cap E [10pt]
text{Leggi Associative} & & (E cup F) cup G &= E cup (F cup G)
& & (E cap F) cap G &= E cap (F cap G) [10pt]
text{Leggi Distributive} & & E cup (F cap G) &= (E cup F) cap (E cup G)
& & E cap (F cup G) &= (E cap F) cup (E cap G) [10pt]
text{Leggi di De Morgan} & & (E cup F)^c &= E^c cap F^c
& & (E cap F)^c &= E^c cup F^c
end{alignat*}
end{document}
