 使用说明：
 1、配置说明：可设置默认数据库路径和默认导出路径
-2、操作说明：支持右键増行/删行，以及按键Insert与Delete
+2、操作说明：支持右键添加行、删除行、插入行等，以及按键Insert与Delete。单元格内Shift+Enter可实现换行输入。
 3、导出文件：以表名命名，相同类型多次导出则覆盖前面文件。默认导出路径为temp，可自定义。
 4、暂存与恢复：暂存界面录入信息，可通过恢复暂存恢复。按表名暂存，每表每日只暂存一个文件。暂存路径为根目录save文件夹。
 5、数据库设置：快速设置数据库链接并记录历史设置。程序启动时读取配置文件的默认数据库链接。
 6、加载表信息：输入表名后：回车、点击工具栏-加载表信息、Alt+F8选择相似，都可以加载相关列信息
-7、注意事项：
+7、右侧搜索面板：支持搜素表名、列名或表说明、列说明。双击搜索列表行，自动加载该表信息(左侧)。
+8、注意事项：
 	a.当表首次创建时，通过导出文件->生成SQL，会自动创建并记录描述信息
 	b.当表已存在时，通过导出文件->生成SQL，仅会更新描述信息

Tools/MyUtils/TextBoxPlaceholder使用说明.md

+# TextBoxPlaceholder 使用说明
+
+## 简介
+`TextBoxPlaceholder` 是一个为 WinForms TextBox 控件提供占位符（Placeholder）功能的辅助类库。
+
+## 功能特点
+- ✅ 自动管理占位符文本的显示和隐藏
+- ✅ 可自定义占位符颜色和正常文本颜色
+- ✅ 提供实际文本内容获取方法（自动排除占位符）
+- ✅ 支持编程方式设置文本和清空操作
+- ✅ 事件绑定自动管理，无需手动处理
+
+## 基本用法
+
+### 方式一：使用构造函数（推荐）
+
+```csharp
+using Tools.MyUtils;
+
+public partial class MyForm : Form
+{
+    private TextBoxPlaceholder _searchPlaceholder;
+    
+    private void InitUI()
+    {
+        // 创建 Placeholder 实例
+        _searchPlaceholder = new TextBoxPlaceholder(
+            this.tbSearch, 
+            "请输入搜索内容，回车确认"
+        );
+    }
+}
+```
+
+### 方式二：使用静态方法
+
+```csharp
+private TextBoxPlaceholder _namePlaceholder;
+
+private void InitUI()
+{
+    // 使用静态方法创建
+    _namePlaceholder = TextBoxPlaceholder.AddPlaceholder(
+        this.tbName, 
+        "请输入姓名"
+    );
+}
+```
+
+## 高级用法
+
+### 自定义颜色
+
+```csharp
+_searchPlaceholder = new TextBoxPlaceholder(
+    this.tbSearch, 
+    "请输入搜索内容",
+    Color.LightGray,      // 占位符颜色
+    Color.Black           // 正常文本颜色
+);
+```
+
+### 获取实际文本内容
+
+```csharp
+// ❌ 错误方式：可能获取到占位符文本
+string text = this.tbSearch.Text;
+
+// ✅ 正确方式：自动排除占位符
+string text = _searchPlaceholder.GetText();
+```
+
+### 编程方式设置文本
+
+```csharp
+// 设置文本
+_searchPlaceholder.SetText("搜索内容");
+
+// 清空文本并恢复占位符
+_searchPlaceholder.Clear();
+```
+
+### 检查是否为占位符状态
+
+```csharp
+if (_searchPlaceholder.IsPlaceholder)
+{
+    // 当前显示的是占位符
+}
+```
+
+## 完整示例
+
+```csharp
+using System;
+using System.Windows.Forms;
+using Tools.MyUtils;
+
+namespace YourNamespace
+{
+    public partial class SearchForm : Form
+    {
+        private TextBoxPlaceholder _searchPlaceholder;
+        
+        public SearchForm()
+        {
+            InitializeComponent();
+            InitUI();
+        }
+        
+        private void InitUI()
+        {
+            // 初始化搜索框 Placeholder
+            _searchPlaceholder = new TextBoxPlaceholder(
+                this.tbSearch, 
+                "请输入搜索关键字，按回车搜索"
+            );
+            
+            // 绑定键盘事件
+            this.tbSearch.KeyDown += TbSearch_KeyDown;
+        }
+        
+        private void TbSearch_KeyDown(object sender, KeyEventArgs e)
+        {
+            if (e.KeyCode == Keys.Enter)
+            {
+                ExecuteSearch();
+            }
+        }
+        
+        private void ExecuteSearch()
+        {
+            // 获取实际搜索内容（自动排除占位符）
+            string searchText = _searchPlaceholder.GetText().Trim();
+            
+            if (string.IsNullOrEmpty(searchText))
+            {
+                MessageBox.Show("请输入搜索关键字！");
+                return;
+            }
+            
+            // 执行搜索逻辑
+            PerformSearch(searchText);
+        }
+        
+        private void BtnClear_Click(object sender, EventArgs e)
+        {
+            // 清空搜索框并恢复占位符
+            _searchPlaceholder.Clear();
+        }
+    }
+}
+```
+
+## 使用场景
+
+### 1. 搜索框
+```csharp
+_searchPlaceholder = new TextBoxPlaceholder(tbSearch, "请输入搜索内容，回车确认");
+```
+
+### 2. 登录表单
+```csharp
+_usernamePlaceholder = new TextBoxPlaceholder(tbUsername, "请输入用户名");
+_passwordPlaceholder = new TextBoxPlaceholder(tbPassword, "请输入密码");
+```
+
+### 3. 筛选输入框
+```csharp
+_filterPlaceholder = new TextBoxPlaceholder(tbFilter, "输入关键字筛选...");
+```
+
+### 4. 配合单选按钮切换
+```csharp
+private void RadBtn_CheckedChanged(object sender, EventArgs e)
+{
+    // 切换模式时清空并恢复占位符
+    _searchPlaceholder?.Clear();
+    
+    // 更新占位符文本（需要时重新创建）
+    if (radBtnTable.Checked)
+    {
+        _searchPlaceholder = new TextBoxPlaceholder(tbSearch, "请输入表名");
+    }
+    else
+    {
+        _searchPlaceholder = new TextBoxPlaceholder(tbSearch, "请输入列名");
+    }
+}
+```
+
+## 注意事项
+
+1. **保持实例引用**：请将 `TextBoxPlaceholder` 实例保存为类成员变量，以便后续操作
+
+2. **获取文本内容**：始终使用 `GetText()` 方法获取实际内容，而不是直接访问 `TextBox.Text`
+
+3. **资源释放**：在窗体关闭时，可选择调用 `Dispose()` 方法解除事件绑定
+   ```csharp
+   protected override void OnFormClosing(FormClosingEventArgs e)
+   {
+       _searchPlaceholder?.Dispose();
+       base.OnFormClosing(e);
+   }
+   ```
+
+4. **多个 TextBox**：可以为每个 TextBox 创建独立的 `TextBoxPlaceholder` 实例
+   ```csharp
+   private TextBoxPlaceholder _placeholder1;
+   private TextBoxPlaceholder _placeholder2;
+   private TextBoxPlaceholder _placeholder3;
+   ```
+
+## API 参考
+
+### 构造函数
+```csharp
+TextBoxPlaceholder(
+    TextBox textBox,           // TextBox 控件
+    string placeholderText,    // 占位符文本
+    Color? placeholderColor,   // 占位符颜色（可选，默认灰色）
+    Color? normalColor         // 正常文本颜色（可选，默认系统文本色）
+)
+```
+
+### 属性
+- `bool IsPlaceholder { get; }` - 当前是否显示占位符
+- `string PlaceholderText { get; }` - 获取占位符文本
+
+### 方法
+- `string GetText()` - 获取实际文本内容（排除占位符）
+- `void SetText(string text)` - 设置文本内容
+- `void Clear()` - 清空文本并恢复占位符
+- `void Dispose()` - 解除事件绑定
+
+### 静态方法
+```csharp
+static TextBoxPlaceholder AddPlaceholder(
+    TextBox textBox, 
+    string placeholderText, 
+    Color? placeholderColor = null, 
+    Color? normalColor = null
+)
+```
+
