Copy this code and paste it in your HTML

# What you NEED in the controller to be able to list someting in a NSTableView in RubyCocoa
#
# Creates the storage array, and another array which contains the names of the columns.
def initialize
  @objects = Array.new
  @columns = ["Column Name 1", "Column Name 2", "Column Name 3", "Column Name 4"]
end
 
# Returns the numbers of rows in the array for NSTableView to display.
def numberOfRowsInTableView(aTableView)
  return @objects.length
end
 
# Uses the @columns array to to enable a flexible number of columns when fetching data.
def tableView_objectValueForTableColumn_row(afileTable, aTableColumn, rowIndex)
  @columns.each do |column|
    if aTableColumn.headerCell.stringValue == column
	object = @objects[rowIndex]
  	return object[column]
    end
  end
end
 
# Usage:
#
# Creates the object that will go into the array. Mind you, the key values must be named the same way as the columns in the NSTableView, which is why it might be a good idea to use the actual @columns array post a identifiers.
object = {
  @columns[0] => "Put...",
  @columns[1] => "...your...",
  @columns[2] => "...values...",
  @columns[3] => "...here"
}
 
# Adds the object to the @objects array
@objects += [object]
 
# Updates the NSTableView after a new post/row has been added to the storage array
@tableViewOutlet.reloadData
