Rearrange Table Columns
The Problem:
After struggling with this table for a couple of hours, I've realized that the second column should really be the first column. Please tell me I don't have to retype both columns!
The Solution:
It's okay, you needn't retype anything. You can move table columns either by dragging or by using Cut and Paste. Getting the hang of dragging columns can take a little practice, so if you have time, create a sample table in a new document and play around with moving the columns. The easiest way to select a column is to move the mouse pointer just above the topmost cell in the target column so that the pointer changes into a black arrow pointing downward, and then click; alternatively, you can click in the column and choose Table 
Select Column. Click anywhere in the selected column, and drag it to the column before which you want it to appear.
