「CSV 转 LaTeX 表格」是什么？What is the CSV to LaTeX Table tool?
把 CSV 或制表符分隔的表格转换成 LaTeX tabular 代码：特殊字符自动转义，带引号的单元格、空行和长度不一的行都按原样处理，引号没闭合时给出错误。本地处理。Turn a CSV or tab-separated table into LaTeX tabular code. Special characters are escaped, and quoted cells, empty rows and uneven rows are kept as they are; an unclosed quote gives an error. Runs locally.
如何使用「CSV 转 LaTeX 表格」？How do I use the CSV to LaTeX Table tool?
在「CSV 转 LaTeX 表格」中，先在上方输入或粘贴内容，然后点击「转换」、「复制」按钮即可。Paste a comma- or tab-separated table into the box and click "Convert". The LaTeX tabular code appears below; click "Copy" to copy it into your document.
哪些字符会被转义？Which characters are escaped?
& % $ # _ { } 前面会加反斜杠，~ 写成 \textasciitilde{}，^ 写成 \textasciicircum{}，\ 写成 \textbackslash{}，粘贴进 LaTeX 后能原样显示。The characters & % $ # _ { } get a backslash, ~ becomes \textasciitilde{}, ^ becomes \textasciicircum{} and \ becomes \textbackslash{}, so the text prints as typed in LaTeX.
空行和空单元格会怎样？What about empty rows and empty cells?
只有空单元格的行（例如一行 "" 或 ,）会保留成空的表格行，不会被删掉；完全空白的行会跳过，并在结果下方说明跳过了几行。A row that has only empty cells (for example a line with "" or ,) is kept as an empty table row, not dropped. Completely blank lines are skipped, and a note below the result says how many.
行长度不一致怎么办？What if rows have different lengths?
不会补也不会删单元格：每行按自己的单元格输出，列格式按最宽的行设置，LaTeX 会把较短行的其余位置留空。结果下方会提示有几行较短。No cells are added or removed: each row is written with its own cells, the column spec follows the widest row, and LaTeX leaves the rest of a shorter row empty. A note below the result says how many rows are short.
引号没闭合会怎样？What happens with an unclosed quote?
会显示错误并指出引号从第几行开始，不会输出可能错位的表格。You get an error naming the line where the quote starts, instead of a table that may be misaligned.
表头里有重名的列会怎样？What if two header cells have the same name?
照常转换，不会改名也不会合并；结果下方会提示哪些列重名（例如“表头里有 2 列都叫「A」（第 1、2 列）”），因为之后按列名查找时只会找到第一列。The table is converted as usual, with nothing renamed or merged, and a note below the result names the repeated columns (for example: the header has 2 columns named "A" (columns 1, 2)), because looking a column up by that name later finds the first one only.
代码或数据会被上传吗？Is my code or data uploaded?
不会。「CSV 转 LaTeX 表格」完全用 JavaScript 在本地运行，适合处理含有密钥、内部接口等敏感内容的数据。No. The CSV to LaTeX Table tool runs entirely in local JavaScript, so it is safe for data containing keys or internal endpoints.
