I see Kalus has the flex grid.
I suppose you mean the
Flexible Table.
In this class, the data is memorized in a List with a String Array with the values for each row.
You would need to add each row.
what method is best to use if data is already in array.
I don't know about a table using an array for the data.
Where does the data come from?
In the Flexible Table there is a routine to directly read csv files to fill the List and the table.
To use the ScrollView2D library you must copy the ScrollView2D.jar and ScrollView2D.xml files to your Additional Libraries folder.
Then, in the IDE Libraries Manager Tab you should see it and check it.
If the IDE is already open when you copy the files you need to right click in the tab and select refresh.
You can add a ScrollView2D in the Designer, it is a CustomView.
In the Flexible Table it is loaded within the class.
