Out of memory using ResultsTable

[fiatlux]

Hi,

I'm trying to display some results in a ResultsTable, but I get very fast out of memory, just by adding 18 empty columns. For instance :

ResultsTable results = new ResultsTable();
for (int i=0; i<18; i++) {
        results.addColumns();
}

I get the message "<Out of memory>" in the log. Is this normal? Does it has something to do with ResultsTable being RAM resident? Or are they disk resident?... Well, I guess I should be able to add more columns than just 18, right? Does someone know how to solve this?
(sorry for my English)

Thanks in advance.

Use the the addValue(String,double) method to display results in the Results table. There is an example at

    http://imagej.nih.gov/ij/plugins/sine-cosine.html

The addValue() method automatically adds columns to the table as needed. The addColumns() method doubles the number of columns so calling it 18 times would result in a table with 150^18 columns!

Ooookay ...
No wonder I was out of memory
I couldn't find any description of the addColumns function, so I just assumed it added one column...
Thanks a lot!
