You don't need us to give you an example, as the example already comes with LV. Go to Help>>Find Examples and search for "excel". You will find an example called "write table to XL". You should note that the example doesn't do that exactly, because it writes a 2D array from 2 to N.
You can modify the example by using only one for loop (instead of nested loops) with a 1D array or by going into the Set Cell Value and modifying it to accept a second cell value for the Cell2 terminal and wiring in a 1D array instead of the single string. If you do modify it, be sure to save it under a different name, so you don't overwrite the original.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials.
Here and
here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read
the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
