LabVIEW
remove same numbers from table
Do you want to remove the lines that have all of the elements the same or just certain columns? What have you tried?
A table is just a 2D array of strings fed to a table indicator.
You need to get rid of this express VI and build a 2D array of strings in a shift register yourself. Now you have full control over each element and can replace rows or columns using "replace array subset" or even insert or delete rows, etc.
(note that your explress VI is configured to not clear data on each call, making the table greow without limits.)
Your description of what you wnt is not very clear. Do you want to keep the last four records, for example?
Sorry, I don't have your drivers. Can you create a simple VI that simulates typical data? How should the table look like as a function of the number of loop iterations?

The vi that I'm making is for reading can signals of the car, in the table are all the data messages sorted, but they keep running and there are only 4 different rows in the table, so I want to see only those four rows.
And there are other data that have way more than four combinations, so I thought to compare the data with the previous data and when it's different, save it into a array. And then compare the results so far in the array with new data, and when there are no differences anymore write it into the table...
Whatever you are writing is pure gibberish and is very difficult to understand. Let me try anyway.
OK, let's look at your table. Apparently, you have four different possible values in column 1 (D1, first column is 0), so that's what you need to identify. Whenever new data arrives, you can just check if that value already exists and then skip adding the new row it to the table. Of course it could also be that some of the other fields are changing too, in this case you could replace the old entry containing the same key in column 1 with the new data.
Should the program stop once you have all unique rows? Do you know the possible D1 values before the program starts?

The table that I showed is the simplest one, but what I want to do in Labview is like in excel (button "remove duplicates" under the tab data).
I don't know what data is going to come in before I'm going to meassure.
But you can always check the incoming data to see if it is a duplicate of an existing entry, and then don't add it to the table.
