8 Color tables in LTEX
The colortbl . . .
Color tables . . .

8.1.

The colortbl package
A
In the previous chapters we learnt how to construct tables in LTEX that could span even to a number of pages. Here we shall see how to obtain color cells in tables, using David Carlisle’s colortbl
package. This package requires the color and array packages.

More Examples . . .

Title Page

The colortbl package provides a number of commands using which one can obtain really
colorful tables. We shall demonstrate each of these with the help of simple examples in the
following sections.

8.1.1.

The columncolor command
Page 2 of 14

The format for the columncolor command is
columncolor[ color model ]{ color }[ left overhang ][ right overhang ]

Color model

It changes the current color to the argument specified until the end of the
current group or the environment. The colors black, white, red, green,
blue, cyan, magenta, and yellow should be predefined by any driver. Colors
can also be defined by a package, as well as by the use of definecolor

command1 .
Color
It is an optional argument, and is like a speciﬁcation to the color model given.
This is particularly convenient if one wants to use a color without deﬁning it
initially.
Left overhang It controls the width of the panel past the widest entry in the column. It is
also an optional argument, and takes the value tabcolsep (in tabular) and
arraycolsep (in array).
Right overhang If ommited it defaults to the left overhang.
We have a few different tables below that will demonstrate a few possibilities using the columncolor
command.

For instance, by using the command definecolor{myblue}{rgb}{.8,.85,1}, you can have the color

myblue.

It is also possible to have colors like the one below! Using multicolumn it is possible to
change the color of specified rows of a table.

The rowcolor command
The rowcolor command is helpful in case a table is maked principally by rows. The arguments in rowcolor are of the form as in columncolor. Here’s an example:

A multicolumn command
overrides the default colors
for both the current row and
column.

begin{tabular}{|l||r|}

rowcolor{lightturquoise} {one} & {two}
rowcolor{honeydew} {three} & {four}
multicolumn{1}{|>{color{blue}columncolor[gray]%
{0.8}}l||}{five} &
multicolumn{1}{|>{columncolor{khaki}}r|}{six}
hline
end{tabular}

8.2.

More colors and tricks
In this section we’ll see how to obtain even more colors: colored rules, colored space between
two rules, and more.
Colored rules can be easily obtained wherever desired by replacing the | with something
like !{color{green}vline}.
The above trick still leaves the spaces between || white. In order to obtain colored space
one can remove the inter glue, and replace it by a colored rule. For instance,
!{color{green}vline}
@{color{yellow}vrule width doublerulesep}
!{color{green}vline}

would change the color of the rules to green, and there would be another yellow rule of
thickness equal to doublerulesep between the two.
arrayrulewidth specifies the ‘thickness’ of the rules. The default is set to 0.4pt and
can be changed by using, for instance, setwidtharrayrulewidth{1pt} to a value of
1pt.

arrayrulecolor takes the same arguments as color. It can be specified at any point

in the table. However, if given in the mid table it affects only the rules that are specified
after that point, and any vertical rules in the table ‘preamble’ keep their original colors.
For example, the command

Go Back

Full Screen

setlengtharrayrulewidth{1pt}arrayrulecolor{blue}

would set the arrayrulewidth to 1pt and the rule color to blue.

Close

doublerulesep specifies the space between the double rules.
Quit

doublerulesepcolor works in the same way as arrayrulecolor, and refers to the

color between double rules.
minrowclearance is used for inserting space at any desired row.

8.3.

Color tables with hhline

The colortbl . . .

There are many advantages of using hhline (hhline package) to draw horizontal rules instead of cline. Firstly, hhline provides more ﬂexibility in producing the rules particularly
because of the way it interacts with the vertical lines. Moreover, sometimes the color of the lines
produced by cline doesn’t appear (rather it’s covered up by the color panels in the following
row). So it becomes more appropriate if one uses the − rule type in a hhline argument.

More Examples . . .

Title Page

The hhline command can be used to produce a single rule, or a double rule. hhline has
arguments very similar to those in the ‘preamble’ of an array or tabular.
=
−
∼
|
:
#

A double hline equal to the column width.
A single hline equal to the column width.
A column with no hline.
A vline which cuts through a double (or single) hline.
A vline which is broken by a double line.
A double hline segment between two vlines.
t The top half of a double hline segment.
b The bottom half of a double hline segment.
∗ *{3}{==#} expands to ==#==#==#, as in the *-form for the preamble.
We now demonstrate an example of the hhline command in the following table:
