rows selection

Ross_ST — Sat, 10 Jun 2023 23:30:47 GMT

Dear all,
I am writing to solve a problem about rows selection in data table I have obtained by import of Current-Voltage data of a set of samples. .

final Data table is made by three columns: Current, Voltage, File Name.

I want to clean the Table from the last row of each group of data corresponding to the same FileName.

It is possible?

Thank you

Ross

I am not quite sure what you mean when you say "I want to clean the Table". Here is a short piece of JSL that will find the last row for each of the FileNames

Names Default To Here( 1 );
dt = Current Data Table();

dt << select where( Row() == Col Max( Row(), :FileName ) );

Is this providing you the information you need?
