When you import data into an Excel Spreadsheet it is not always aligned in good proportion to the rest of the document. Here is the quick and easy way to line it up.
当您将数据导入Excel电子表格时，它并不总是与文档的其余部分成比例地对齐。 这是排列它的快速简便的方法。
After you have imported your data select all columns and rows; choose A hold down your shift key and go over to the end of your data so everything is highlighted.
导入数据后，选择所有列和行； 选择A并按住Shift键，然后移至数据末尾，以便突出显示所有内容。
Now right-click on the highlighted fields and from the sub menu choose Format Cells.
现在，右键单击突出显示的字段，然后从子菜单中选择“设置单元格格式”。
In the Format Cells window click the Alignment tab, choose Center from the drop down box under Horizontal and click OK.
在“设置单元格格式”窗口中，单击“对齐”选项卡，从“水平”下的下拉框中选择“居中”，然后单击“确定”。
Now all of the data will align in the center of each cell to make the data more presentable. This is especially handy when you are printing out the reports.
现在，所有数据将在每个单元格的中心对齐，以使数据更易于呈现。 当您打印报告时，这特别方便。
