 # TabEditor
 
 这个是一个简约的文本文件编辑工具，主要用于编辑以制表符分隔的数据文本文件。与使用Excel编辑相比，该程序可以确保文本文件的格式和内容不会发生改变，提供更可靠的编辑功能。它简约直观的界面使用户能够轻松地加载、编辑和保存这类文本文件。

+
+## TODO
+
+- 自动适配文本文件本身的字符编码格式
+
+以下功能不知道当前用的 tablewidget 是否支持
+- 表格内容搜索
+- 冻结行、列
+- 隐藏行、列
+
+
+
+可能需要增加的功能：
+
+- 转换换行符为可见的“\n”——因为由制表符分隔数据的纯文本文件，不建议直接使用换行（读取改文本的使用场景比较特殊）
+
+
+
+
+
+## Qt程序打包
+
+1. 使用Qt命令行程序：Qt 5.14.2 (MinGW 7.3.0 64-bit)
+
+进入Qt程序的build目录下的exe所在路径，输入：
+```shell
+windeployqt TabEditor.exe
+```
+
+2. 使用此项目中的 [packaging.bat](https://begin2019.com:3000/Crimson/TabEditor-Qt/src/branch/main/packaging.bat) ，双击运行 根据提示操作即可。
+
+   > 前提：安装了Qt 5.14.2 (MinGW 7.3.0 64-bit)
