[Tex/LaTex] Tabu table text-colored header: vertical and horizontal alignment, one line and word wrap cases

colorhorizontal alignmenttablestabuvertical alignment

We have a latex tabu table with custom header's style: it has different alignment, color and shape from other table rows.

BTW XeLaTeX is used.

Header could be short on length, see the pictures and minimal working example (MWE, in the end).

It is neccesarry to apply following style to header text:

bold;
aligned to horizontal center;
aligned to vertical center (both for one line or word wrapped cases);
custom color is #0070C0;

Desired result

We have applied \rowfont{} command to the first tabu table row as in answer https://tex.stackexchange.com/a/26363/123948

\taburulecolor{DarkBlue}
\tabulinesep = 1mm
\begin{tabu} to 170 mm {
    |X[2]       %  |X[2,m]
    |X[1.5]     %  |X[1.5,m]
    |X[0.6, C]  %  |X[0.6, C,m]
    |X[2]       %  |X[2,m]
    |X[0.6, C]| %  |X[0.6, C,m]|
    }
\rowfont{\centering\bfseries\color{Blue}}
%...

and:

text became bold using \bfseries;
aligned to horizontal center using \centering;
color is \definecolor{Blue}{HTML}{1C8CCC};
tried tabu's m colunm type to align to vertical center, but it works only in wrapped case (one-line is not) and it affects to whole table, but we need header only.

Actual result
without m type because it affects to the whole table

Questions

How to align vertically only header text using \rowfont{} (or other way)?
Are horizontal alignment and coloring of header row implemented correctly or there are better ways?

Minimal working example

XeLaTeX is used.

Edit:

tabu is nice package, reach of features but unfortunately it is buggy and no more maintained.
problem is in use color{...} (independent of used latex engine)
as workaround see if the following solution is acceptable for you
- remove \rowcolor{...}
- define new commanad (see mwe below, let its name be \ch (column header) which carry about boldface font, color of fonts and vertical spacing of cells content

\documentclass[10pt, oneside, a4paper]{report}
\usepackage[left=2cm,right=1.5cm,
    top=2cm,bottom=2cm,bindingoffset=0cm]{geometry}
\usepackage{indentfirst}

\usepackage[svgnames]{xcolor}
\definecolor{DarkBlue}{HTML}{0070C0}
\definecolor{Blue}{HTML}{1C8CCC}
\usepackage{multirow}
%\usepackage{polyglossia} % i haven't this fonts
%\setmainfont[Ligatures=TeX]{Arial}% i haven't this fonts

\newcommand\ch[1]{\centering                        % <--- added
    \begin{tabular}{@{}>{\color{Blue}\bfseries}c@{}}
                    #1
    \end{tabular}
                  }

\begin{document}
\taburulecolor{DarkBlue}
\tabulinesep=1mm       
\begin{tabu} to 170 mm {
    |X[2]       %  |X[2,m]
    |X[1.5]     %  |X[1.5,m]
    |X[0.6, C]  %  |X[0.6, C,m]
    |X[2]       %  |X[2,m]
    |X[0.6, C]| %  |X[0.6, C,m]|

\ch{Status}
    & \ch{Visual indication:\\ color and\\ indication type}

[Tex/LaTex] Many vertical alignment problems with tabu table

The spacing
tabu, as most other table packages, has some problem with spacing, especially when you are using list-environments. Therefore, we all longing for v 2.9. Try using \tabulinesep=1.3mm and remove the nolistsep from the two first listings (or give topsep= a small value (f.ex. 0.1ex). After \textit{Operation selector} put a \newline. Listings in tables are challenging.

I have tinkered a bit more with your code. The bad spacing around lists are not tabu’s fault, but the itemize-environment adding, in this setting, unnecessary space. I solved this by including the itemize-environment in a 5 cm wide \parbox and reducing the topsep to 0.1ex. If you have necessary skills, you may read the width of the fourth column from the .aux-file.

The problem with the heading is your setting of column 2 and 3. It is too narrow. I increased the width of these columns and the headings lined up. As @hakaze point out, only the last column need to be a X column; the cells in the three first columns are only one line. Use ordinary l- and c-columns instead, and the headings line up nicely.

I also added a \strut to the first column, giving the heading more depth.

Complicated table is difficult, and you have to be prepared for fine tuning whatever package you are using.

Here is the code for a new MWE:

     |[1pt gray] l    % or X[2m]
     |[1pt gray] X[8,lm]  % I suggest you set the column ragged right
     |[1pt blue] } \everyrow{\extrarowsep=^2pt\tabucline[1pt gray]-}

[Tex/LaTex] Vertical and horizontal alignment with tabu package

tabu also allows the use of negative coefficients to use on X columns so that one can have all the features of the X columns without the scaling part. This therefore eliminates the need to the raisebox "hack". All you need is change your c column to X[-1,m,c]

\documentclass{article}
\usepackage{tabu} 

\begin{document}
\noindent
\begin{tabu}{|X[m,c]|X[-1,m,c]|X[m,c]|}
    Left content centered \linebreak between margin and title &
    \Huge Title &
    Right content \linebreak also centered
\end{tabu}

\end{document}
