Graphics, Figures & Tables ⇒ How to highlight the row in a thinner way? and column

[gcheer3]

Hello,

Anyone please give me some suggestions on this problem.
I have a table as follows:

Code: Select all

\begin{tabular}{ccccr}
    \hline
$k$ &  $x_1^k$    &   $x_2^k$  & $x_3^k$   & remarks  \\
    \hline
0   & -0.3 & 0.6 & 0.7  &  \\[0.2ex]
\rowcolor[gray]{.8}
1   & 0.47102965 & 0.04883157 & -0.53345964  & *\\[2.5ex]
2   & 0.49988691 & 0.00228830 & -0.52246185 & $s_3$ \\[0.2ex]
\rowcolor[gray]{.8}
3   & 0.49999976 & 0.00005380 & -0.52365600  & \\[2.5ex]
4   & 0.5 & 0.00000307 & -0.52359743  & $\epsilon < 10^{-5}$ \\[0.2ex]
5   & 0.5 & 0 & -0.52359878  & $\epsilon < \xi $ \\[0.2ex]
    \hline
\end{tabular}

I purposely make a bigger space between every two rows(every two number is sort of in one group). So "\\[2.5ex]" did the work. But now I want to highlight two rows with 'k=1' and 'k=3'. I used \rowcolor[gray]{.8}, unfortunately, since there is a gap between 'k=1' and 'k=2', the grey highlight area is too wide. In other words, is there is a way that I can still highlight the row 'k=1', but only tightly highlight the row, not so much area under?

Also, how can I just simply highlight the fourth column in the table including the column title 'x_3^k'. Somehow, I cannot make it work.

Many thanks!

Hi,

for the first issue, you can add two fictitious rows; for the second problem, use \columncolor and the >{...} construct (see the array package documentation); depending on the actual coloring pattern required you might also need to use \cellcolor (my code includes two possibilities):
