Border for one column in Latex
TeX - LaTeX Asked by ali-sezar on August 13, 2021
I am new to latex and I have trouble to find out what is going on in table environment.
I have a table and want to separate every 3 column with each other to look like this:
But my tex is like below:
documentclass{article}
usepackage{placeins}
usepackage{booktabs ,float}
begin{document}
begin{table}
begin{tabular}{ccclllllllll}
hline
multicolumn{1}{|c|}{textbf{i}} & multicolumn{1}{c|}{textbf{Z_i}} & multicolumn{1}{c|}{textbf{U_i}} & multicolumn{1}{c|}{textbf{i}} & multicolumn{1}{c|}{textbf{Z_i}} & multicolumn{1}{c|}{textbf{U_i}} & multicolumn{1}{c|}{textbf{i}} & multicolumn{1}{c|}{textbf{Z_i}} & multicolumn{1}{c|}{textbf{U_i}} & multicolumn{1}{c|}{textbf{i}} & multicolumn{1}{c|}{textbf{Z_i}} & multicolumn{1}{c|}{textbf{U_i}} hline
0 & 7 & - & 5 & 10 & 0.652 & 10 & 9 & 0.563 & 15 & 4 & 0.250
1 & 6 & 0.375 & 6 & 5 & 0.313 & 11 & 0 & 0.000 & 16 & 7 & 0.438
2 & 1 & 0.063 & 7 & 12 & 0.750 & 12 & 3 & 0.188 & 17 & 6 & 0.375
3 & 8 & 0.500 & 8 & 15 & 0.938 & 13 & 2 & 0.125 & 18 & 1 & 0.063
4 & 11 & 0.688 & 9 & 14 & 0.875 & 14 & 13 & 0.813 & 19 & 8 & 0.500
end{tabular}
end{table}
end{document}
Thanks in advance for the answers.

Removing all the occurences of multicolumn{1}{|c|} in combination with using begin{tabular}{ccc|ccc|ccc|ccc} should result in an output closer to the expected one. Personally, I recommend to not use vertical lines in a table. Instead you could use horizontal white space in combination with interrupted horizontal lines from the booktabs package in order to create a visual separation between teh 4 blocks in your table. For an improved alignment of numbers in your table, you may also want to consider using S type columns from siunitx.

I suggest you get rid of the multicolumn{1}{c}{...} wrappers, employ an array environment instead of a tabular environment, and replace all instances of textbf with bm. I would also align the numbers in the "Z" columns on their (implicit) decimal markers.
documentclass{article}
usepackage{siunitx,bm}
usepackage{newtxtext,newtxmath} % optional: Times Roman text and math fonts
begin{document}
begin{table}
[
begin{array}{@{} *{3}{c S[table-format=2.0] c|} ccc @{}}
hline
bm{i} & {bm{Z}_i} & bm{U}_{!i} & bm{i} & {bm{Z}_i} & bm{U}_{!i} &
bm{i} & {bm{Z}_i} & bm{U}_{!i} & bm{i} & {bm{Z}_i} & bm{U}_{!i}
hline
0 & 7 & textup{--} & 5 & 10 & 0.652& 10& 9 & 0.563& 15& 4 & 0.250
1 & 6 & 0.375& 6 & 5 & 0.313& 11& 0 & 0.000& 16& 7 & 0.438
2 & 1 & 0.063& 7 & 12 & 0.750& 12& 3 & 0.188& 17& 6 & 0.375
3 & 8 & 0.500& 8 & 15 & 0.938& 13& 2 & 0.125& 18& 1 & 0.063
4 & 11 & 0.688& 9 & 14 & 0.875& 14& 13 & 0.813& 19& 8 & 0.500
end{array}
]
end{table}
end{document}
