我正在用 Ti 整理一个多月日历钾Z 并且看到月份标签中有一些尴尬和不受欢迎的对齐，尽管使用了month label above centered。特别是，月份标签似乎只在第一个六列，而不是全部七：
我在下面以最小的上下文重现了我的代码。 两个问题：这是怎么回事？我该如何纠正这种对齐？

\ifnum\pgfcalendarcurrentweekday=6
\c@pgf@counta=0

\c@pgf@counta=\pgfcalendarcurrentweekday

答案2
我认为这是 pgf 中的一个错误。您使用键month label above centered将月份名称放在日期上方，这在文件中定义tikzlibrarycalendar.code.tex为
\tikzset{month label above centered/.style={%
execute before day scope={%
\ifdate{day of month=1}{%
{
\pgfmathsetlength{\pgf@xa}{\tikz@lib@cal@xshift}%
\pgf@xb=\tikz@lib@cal@width\pgf@xa%
\advance\pgf@xb by-\pgf@xa%
\pgf@xb=.5\pgf@xb%
\pgftransformxshift{\pgf@xb}%
\pgftransformxshift{-1.5ex}%
\pgfmathsetlength{\pgf@y}{\tikz@lib@cal@yshift}%
\pgftransformyshift{1.25\pgf@y}
\tikzmonthcode%
}
}{}},
every month/.append style={anchor=base}
}}
显然，有一个额外的\pgftransformxshift{-1.5ex}，这是造成错位的原因。如果您month label above centered在代码中用上面的定义替换，但删除\pgftransformxshift{-1.5ex}，您将获得正确的对齐。这是您修改后的 MWE：
\documentclass[letterpaper]{article}
\usepackage[utf8]{inputenc}

\makeatletter%
\tikzstyle{week list sunday}=[
% Note that we cannot extend from week list,

% On first of month, except when first date in calendar.
\pgfmathsetlength{\pgf@y}{\tikz@lib@cal@month@yshift}%
\pgftransformyshift{-\pgf@y}
}}{}%

execute at begin day scope={%
% Because for TikZ Monday is 0 and Sunday is 6,
% we can't directly use \pgfcalendarcurrentweekday,
% but instead we define \c@pgf@counta (basically) as:
% (\pgfcalendarcurrentweekday + 1) % 7
\pgfmathsetlength\pgf@x{\tikz@lib@cal@xshift}%
\ifnum\pgfcalendarcurrentweekday=6
\c@pgf@counta=0
\else
\c@pgf@counta=\pgfcalendarcurrentweekday
\advance\c@pgf@counta by 1
\fi
\pgf@x=\c@pgf@counta\pgf@x
% Shift to the right position for the day.
\pgftransformxshift{\pgf@x}
},
execute after day scope={
% Week is done, shift to the next line.
\ifdate{Saturday}{
% But not if it's already the last day of the month.
\ifdate{end of month=1}{}{
\pgfmathsetlength{\pgf@y}{\tikz@lib@cal@yshift}%
\pgftransformyshift{-\pgf@y}

}{}%
