Excel学习第三天:基础操作
合并单元格：将多个单元格合并成一个单元格。选中要合并的单元格，在功能区找到“开始”菜单栏，点击“合并”。
取消合并：合并后的单元格重新拆分成原来的多个单元格。选中要拆分的单元格，在功能区找到“开始”菜单栏，点击“合并”，合并后的单元格即可恢复为原来的单个单元格状态。
插入行或列：鼠标悬停在列标（ABCD）或行标（1234）上面，点击鼠标右键，即可在选中的行/列前面或后面插入任意数目的行/列。
调整行高或列宽：顾名思义，行可以调整行高度，列调整其列宽度，从而调整单元格的大小。
两个方法，一个粗放 ，一个精准。
粗放的方法是鼠标悬停在列标（ABCD）或行标（1234）的框线处，这时候可以看到鼠标指针变成下图所示带左右或上下箭头的十字框，
这时候摁住鼠标左键不松手，上下左右移动即可调整宽度或高度，双击左键自动适配内容宽度。
精准的办法是，鼠标悬停在列标（ABCD）或行标（1234）上面，点击鼠标右键，找到列宽/行高，在弹出的窗口中输入合适的列宽/行高即可。
