POI 设置单元格背景颜色

本文介绍了一个使用Apache POI库为Excel单元格填充各种颜色的Java示例。示例展示了如何通过IndexedColors枚举来设置单元格背景色。

This example shows you Excel cell fills and colors using Apache POI.

In our example i have used all the possible colors and set it as Fills background colors of cells.

Below is the example code.

package com.java.connect.poi;

import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.ss.usermodel.Cell;

### MathPix工具介绍 Mathpix Snipping Tool 是一款强大的数学公式识别工具,从最初的原型发展至今已经历了多次迭代和功能增强[^1]。该工具不仅能处理简单的数学表达式,还可以应对复杂的数学模型以及多行公式,并且支持手写公式的识别。 这款应用程序通过不断的科技创新与用户反馈改进,在学术研究和技术领域赢得了良好声誉,成为许多科研人员不可或缺的工作伙伴之一。除了基本的功能外,Mathpix 还提供了多种高级特性来满足不同用户的特定需求。 ### 使用方法 #### 安装与启动 为了使用 Mathpix Snipping Tool ,首先需要下载安装程序并按照提示完成设置过程。一旦成功安装后即可随时调用此应用来进行截图操作。 #### 截取屏幕上的公式图像 当遇到想要转换成 LaTeX 或 AsciiMath 的图片时,只需打开软件界面按下快捷键(默认为 `Ctrl+Alt+M`),此时鼠标指针会变为十字形状以便于选取目标区域;框选所需部分之后松开按键即刻上传至云端服务器等待进一步分析处理。 #### 获取LaTeX代码片段 经过短暂几秒钟的时间延迟过后,所截获的内容将以纯文本形式显示出来供复制粘贴到其他编辑器当中继续编写文档或是分享给他人查看交流之用。 ```python import pyperclip # 假设已获取到LaTeX字符串 stored_in_variable named latex_code pyperclip.copy(latex_code) print("LaTeX code has been copied to clipboard.") ``` 对于希望深入探索更多可能性的用户来说,可以考虑查阅官方提供的扩展插件——如用于解析Markdown文件内的公式标记语法的库 **mathpix-markdown-it** [^2] ——这将进一步提升工作效率和个人体验感。
