我正在使用Overleaf 海报模板创建海报。我有四列，我想要一个可以覆盖四列的警告框。我不明白为什么警告框右侧的空间比左侧的空间大。我\centering之前试过警告框，\begin{center}但都不起作用。检查模板所基于的 beamerthemeconfposter.sty 中的间距和边距，我仍然没有弄清楚。
这是我的代码：
\documentclass[final]{beamer}
\usepackage[scale=1.24]{beamerposter} % Use the beamerposter package for laying out the poster
\usetheme{confposter} % Use the confposter theme supplied with this template
\setbeamercolor{block title}{fg=ngreen,bg=white} % Colors of the block titles
\setbeamercolor{block body}{fg=black,bg=white} % Colors of the body of blocks
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70} % Colors of the highlighted block titles
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10}
% Define the column widths and overall poster size
% To set effective sepwid, onecolwid and twocolwid values, first choose how many columns you want and how much separation you want between columns
% In this template, the separation width chosen is 0.024 of the paper width and a 4-column layout
% onecolwid should therefore be (1-(# of columns+1)*sepwid)/# of columns e.g. (1-(3+1)*0.024)/3= 0.301
% Set twocolwid to be (2*onecolwid)+sepwid = 0.464
% Set threecolwid to be (3*onecolwid)+2*sepwid = 0.708
% Set fourcolwid to be (4*onecolwid)+3*sepwid = 0.88 + 0.072=
\newlength{\sepwid}
\newlength{\onecolwid}
\newlength{\twocolwid}
\newlength{\threecolwid}
\newlength{\fourcolwid}
\setlength{\paperwidth}{33.1in} % A0 width: 46.8in
\setlength{\paperheight}{46.8in} % A0 height: 33.1in
\setlength{\sepwid}{0.024\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.22\paperwidth} % Width of one column
\setlength{\twocolwid}{0.464\paperwidth} % Width of two columns
\setlength{\threecolwid}{0.708\paperwidth} % Width of three columns
\setlength{\fourcolwid}{0.952\paperwidth} % Width of three columns
\setlength{\topmargin}{-0.5in} % Reduce the top margin size

\begin{column}{\sepwid}\end{column} % Empty spacer column
\begin{column}{\fourcolwid} % The first column
\begin{alertblock}{Objectives}

}
谢谢！

beamerposter警告块和标题没有居中，因为手动弄乱纸张尺寸是个坏主意 -如果您想更改纸张格式，请使用软件包提供的选项。
并且与代码中的注释相反，graphicxbeamer 不需要它，因为 beamer 已经为您加载了它。
