Databricks中Jupyter Notebook快捷键复制代码缺失问题求助

问题现象 #

在Databricks浏览器端工作区的Jupyter Notebook中，使用Ctrl+C复制单元格内代码后，Ctrl+V粘贴到其他单元格时，代码中间部分会被省略号…替代。右键复制后再粘贴可正常获取完整代码，其他用户使用相同快捷键操作无异常，更换键盘后问题仍存在。

示例：
原代码：

spark.sql(f"""
select 
  0 as somecolumn_0,
  1 as somecolumn_1,
  2 as somecolumn_2,
  3 as somecolumn_3,
  4 as somecolumn_4,
  5 as somecolumn_5,
  6 as somecolumn_6,
  7 as somecolumn_7,
  8 as somecolumn_8,
  9 as somecolumn_9,
  10 as somecolumn_10,
  0 as somecolumn_11,
  1 as somecolumn_12,
  2 as somecolumn_13,
  3 as somecolumn_14,
  4 as somecolumn_15,
  5 as somecolumn_16,
  6 as somecolumn_17,
  7 as somecolumn_18,
  8 as somecolumn_19,
  9 as somecolumn_20,
  10 as somecolumn_21
""")

粘贴后代码：

spark.sql(f"""
select 
  0 as somecolumn_0,
  1 as somecolumn_1,
  2 as somecolumn_2,
  3 as somecolumn_3,
  4 as somecolumn_4,
  5 as somecolumn_5,
  6 as somecolumn_6,
  7 as somecolumn_7,
…  7 as somecolumn_18,
  8 as somecolumn_19,
  9 as somecolumn_20,
  10 as somecolumn_21
""")

可能原因 #

• 浏览器扩展干扰：剪贴板管理、文本格式化类的浏览器扩展，可能自动截断或修改复制的长文本内容
• 浏览器剪贴板设置异常：部分浏览器的剪贴板优化功能（如自动压缩长文本）触发了错误处理逻辑
• Databricks个人配置损坏：工作区的Notebook编辑偏好设置出现局部异常
• 浏览器缓存/本地存储冲突：针对Databricks站点的缓存、Cookie或本地存储数据异常，导致复制逻辑出错

解决办法 #

• 排查浏览器扩展：暂时禁用所有浏览器扩展，测试复制粘贴是否正常；若恢复正常，再逐个启用扩展，定位冲突的插件并移除/禁用
• 重置浏览器剪贴板设置：
  • Chrome：进入设置页面，搜索“剪贴板”，重置剪贴板权限及相关优化选项
  • Firefox：在隐私与安全设置中，检查并重置剪贴板相关权限
• 重置Databricks编辑配置：登录Databricks工作区，进入用户设置页面，找到Notebook编辑偏好选项，恢复为默认设置
• 清除浏览器站点数据：针对Databricks站点，清除缓存、Cookie和本地存储数据，重启浏览器后重试
• 隐私模式测试：打开浏览器隐私/无痕窗口，登录Databricks后测试复制粘贴，排除本地配置的影响
• 更换浏览器测试：尝试使用Firefox、Edge等其他浏览器，确认是否为特定浏览器的兼容性问题
