not knowing what exactly you need, there are many examples.....try  "2D array" in the forum search  Smiley Wink

 

there should be something close to what you need, try it....and get back to us with a VI and any problems you have encountered with it.

What are you trying to do with the data?  If you are doing calculations, you will first need to convert from a 2D Array of strings into a 2D Array of numerics, most likely DBL.  You can do all kinds of fun stuff from there.

you are building your table as an indicator...couldn't you just wire directly the data directly into your calculations or make references to them from your sub.vi?

I can connect it directly, but i need to know how to take value from exact colum and make calculations with it(average value from all colums, devation and same...).

Hi Nenoo,

 

to "take values from table" you need to index array elements. Usually IndexArray is the function you need.

(Or autoindexing in a loop, depending on your task which isn't defined very well until now.)

 

This is pretty basic LabVIEW knowledge so I advise you to take the free online courses offered by NI!

Best regards,
