/**
* Creating tables to be printed to the console.
*
* Every ezcConsoleTable object can be accessed as if it was a multidimensional,
* numerically indexed array. The first dimension represents the rows of the
* table, so $table[0] gives you access to the first row of the table, which is
* represented by a {@link ezcConsoleTableRow} object. You can access its
* properties directly, using e.g. $table[0]->format. The second dimension gives
* you direct access to the cells of your table, like $table[0][0] accesses the
* first cell in the first row of your table. You can access its properties
* diretly here, too. This works like e.g. $table[0][0]->format. Table row and
* cell objects are created on the fly, when you access them for the first time.
* You can also create them as if you simply create new array elements. E.g.
* $table[] creates a new row in the table.
*
* <code>
* // Initialize the console output handler
* $out = new ezcConsoleOutput();
* // Define a new format "headline"
* $out->formats->headline->color = 'red';
* $out->formats->headline->style = array( 'bold' );
* // Define a new format "sum"
* $out->formats->sum->color = 'blue';
* $out->formats->sum->style = array( 'negative' );
*
* // Create a new table
* $table = new ezcConsoleTable( $out, 60 );
*
* // Create first row and in it the first cell
* $table[0][0]->content = 'Headline 1';
*
* // Create 3 more cells in row 0
* for ( $i = 2; $i < 5; $i++ )
* {
* $table[0][]->content = "Headline $i";
* }
*
* $data = array( 1, 2, 3, 4 );
*
* // Create some more data in the table...
* foreach ( $data as $value )
* {
* // Create a new row each time and set it's contents to the actual value
* $table[][0]->content = $value;
* }
*
* // Set another border format for our headline row
* $table[0]->borderFormat = 'headline';
*
* // Set the content format for all cells of the 3rd row to "sum"
* $table[2]->format = 'sum';
*
* $table->outputTable();
* </code>
