I've got few tables created with few packages included booktabs
where I use the command \rowcolors
from the xcolor
package. But in the last I notice that the colour is wider that the lines of the same table. Since the way to create the tables and the packages used in all are the same I don't know what could happen. This is my MWE:
\documentclass[fontsize=10pt,paper=letter,headings=big,bibliography=totoc,DIV=8]{scrbook}
\KOMAoptions{headsepline=true,draft=false}
\usepackage{typearea}
\usepackage[usenames,dvipsnames,x11names,table]{xcolor}
\usepackage[single=false,macros=false,xspace=false]{acro}
\usepackage[spanish,mexico]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[sc,osf]{mathpazo}
\usepackage[defaultsans]{opensans}
\usepackage{array,multirow,tabularx,ragged2e,booktabs}
\newcolumntype{Y}{>{\RaggedRight\arraybackslash\hspace{0pt}}X}
\newcolumntype{C}{>{\centering\arraybackslash\hspace{0pt}}X}
\usepackage{rotating}
\usepackage{colortbl}
\usepackage[per-mode=symbol]{siunitx}
\DeclareSIUnit\poise{P}
\DeclareSIUnit\stokes{St}

Both tables have the same problem, but the second one has a difficult more: I try to add a column with text rotated 90º, but I don't know how to fit it for use the same colour scheme without cover with the colour part of that rotated column... if it is possible.
