How to use Spanish accents in LaTeX
A short example showing how to set up the correct packages in your preamble in order to use Spanish accents in your LaTeX documents.
Using the CTeX Package on Overleaf (在Overleaf平台上使用CTeX)
The CTeX package (http://ctan.org/pkg/ctex) provides a style common in Chinese typsetting. However, many CTeX-based templates uses fonts bundled with Windows, which are unavailable on Overleaf.
This example shows how the CTeX package can be configured to use fonts installed on Overleaf. The default Fandol font works if you compile with XeLaTeX or LuaLaTeX. You may upload your own OTF/TTF fonts and use those also, but do be aware that Chinese font files are usually quite large!
应该有很多 CTeX 用户把自己的文件上载到 Overleaf 后，才发现由于没有 Windows 默认字体，文件不能编译而抓狂吧。不过这是可以改正的。在这个范例里，我们挪用了 Overleaf 伺服器上已有的字体，CTeX 文件就可以编译了。
Tracking changes in LaTeX with "changes" package
The changes package, distributed with TeX Live, allows the user to manually markup changes of text, such as additions, deletions, or replacements. Changed text is shown in a different colour; deleted text is crossed out. The package allows definition of additional authors and their associated colour. It also allows you to define a markup for authors or annotations. (Here's another customised example using avatars for the author annotations.)
A longtable + tabularx example
The ltxtable combines the functionalities of longtable and tabularx.
The trick is to put your longtable using tabularx-style X columns in a separate file, and then include this file in your main document using the command \LTXtable.
Automatic Acronym List in LaTeX
A simple example of creating a list of acronyms using the acronym package, which supports auto-expansion on first mention, and shortening on subsequent mentions.
