Are you sure the tab that contains the Table class is actually called Table?

Both the tab name and the filename have to be the same I believe.

I have this problem frequently when using tabs, so I'm interested in the solution. I usually just don't use tabs to avoid it. Could it be a pug in the PDE?

/tmp/build35588.tmp/Temporary_681_3299.java:8:23:8:27: Semantic Error: Type "Table" was not found.

I just re-typed everything and I still get the error.  Here's the code:
=============

PImage mapImage;
Table locationTable;
int rowCount;

void setup(){
 size(640,480);
 mapImage = loadImage("map.png");
 locationTable = new Table("locations.tsv");
 rowCount = locationTable.getRowCount();
}

void draw(){
 background(255);
 image(mapImage, 0, 0);
 
 smooth();
 fill(192,0,0);
 noStroke();
 
 for (int row = 0; row < rowCount; row++){
   float x = locationTable.getFloat(row,1);
   float y = locationTable.getFloat(row,2);
   ellipse(x,y,9,9);
 }
}
============

I have performed: Sketch, Add File, ... for both map.png and Table.pde.  When I do this to Table.pde (which is downloaded from benfry.com) it asks "do you want to replace Table.pde?" - I click yes.

Is there something else I should be doing to let this project know about the Table.pde class?

Again, please pardon my ignorance.  I'm very new to Java and Processing.

When you do "Open..." you should only open the .pde file that matches the directory, so if in your processing directory you have a sketch called "MySketch", go into the MySketch directory and open MySketch.pde. This should also open every other .pde file in that directory and put them in tabs. These will all then be lumped together behind the scenes when the sketch is run, and it should "Just Work"
