Define the number of rows and columns by setting the Number of Rows and Number of Columns parameters, and leave the Cell Size Width and Cell Size Height parameters empty or set them to 0.Define the cell width and height as above, but additionally enter the number of rows and columns.When the tool executes, it calculates the number of rows and columns needed to cover the extent of the fishnet. Define the cell width and height with the Cell Size Width and Cell Size Height parameters and leave the Number of Rows and Number of Columns parameters empty or set them to 0.There are four methods to specify the number of rows and columns: If you have set the extent of the fishnet using one of the first three methods described above, you will need to set the number of rows and columns.
