Hi vwsj,
A table is a specific object in LabVIEW that takes a 2-D string data type; the code that Cory K and I showed you will not provide anything related to a table. The code I uploaded an image of uses a single string indicator. The string it displays is a single long string with your values separated by carriage returns. If you want to review your data at a later point in time, you will want to record it to a measurement file or text file.
It seems that you are trying to implement a gate in software. For your application, you may want to consider using the "Trigger and Gate" Express VI instead of the hard coded version that Cory K and I showed you earlier. Once you have filtered your data appropriately with this VI, you can use the "Write to Measurement File" Express VI or the "Write to Text File" VI with its appropriate support VIs. (There are examples on this.) Using these techniques, you can choose to make a new file for each gun shot or to append new data to a single file.
