excel 单元格字符数限制(from microsoft support)
来源:互联网 发布:ubuntu安装主题包 编辑:程序博客网 时间:2024/06/06 17:49
Microsoft Excel 版本中,一个单元格可包含多达 32,767 个字符。但是,如果某单元格中包含的字符多于 1,024 个,则应遵循以下规则:
- 大约第 1,024 个字符之后的字符不显示在单元格中;不过,在编辑或选择该单元格时,它们会出现在编辑栏中。
- 尽管不会显示大约第 1,024 个字符之后的字符,但可以使用工作表函数(例如 RIGHT 和 MID 函数)和宏命令(例如“字符”属性)检测并操作这些字符。
- 如果复制包含 1,024 个以上字符的单元格,然后将其粘贴到另一单元格中,则会将所有字符粘贴到新的单元格中。不过,大约第 1,024 个字符之后的字符不会在目标单元格中显示。
- 无法打印单元格中大约第 1,024 个字符之后的字符,且这些字符也不会在打印预览中显示。
注意:增加工作表行高和列宽,或修改系统的显示设置后,可以看到的字符数将多于 1,024 个。
示例
要了解此问题,请按照下列步骤操作:
- 在新工作表的单元格 A1 中,键入以下公式:=REPT("w",1024)&"xyz"
- 选中单元格 A1,单击“格式”菜单上的“单元格”。
- 单击“对齐”选项卡。单击以选中“自动换行”复选框,然后单击“确定”。
- 在“格式”菜单上,指向“列”,然后单击“最适合的列宽”。
请注意,您只能在单元格 A1 中看到“w”字符,该单元格结尾处的“xyz”字符不会显示。 - 在单元格 A2 和 A3 中键入以下公式:A2:=RIGHT(A1,3)单元格 A2 中的公式返回结果“xyz”,即单元格最右侧的三个字符。单元格 A3 中包含数字 1027,即单元格 A1 中的字符数。
A3:=LEN(A1) - 将单元格 A1 中的公式更改为:=REPT("w",1023)&"xyz"
您可以看到 1,023 个“w”字符及其后的“x”字符。因为存在 1,024 个字符的限制,所以不会显示“yz”字符。单元格 A3 中的公式现在显示 1026,即单元格 A1 的长度。
