To Set Labeling Datums
1. Click Design and click the arrow next to Rows and Columns.
2. Click Set Sheet Labeling Datum.
3. Click in the sheet to select two corner points for the first and second labeling datums. The Set Sheet Columns and Rows dialog box opens.
* 
The two corner points define a virtual bounding box used to place the location set labels. The column labels are positioned along the top and bottom of the box. The first probed corner indicates where the numbering starts from, to allow for forward or reverse numbering in each axis. For example, probing in the top right will cause the numbering to run right to left in the horizontal axis and top to bottom in the vertical axis.
a. First labeling datum
b. Second labeling datum
4. Set the number of rows and columns in the Set Sheet Columns and Rows dialog box.
5. Click OK.
