-Функция createHelloWorldSession создает структуру реализующую интерфейс SessionContent:
+1) IP адрес по которому будет доступно приложение (в нашем примере это "localhost:8000")
+2) Фуекция создает структуру реализующую интерфейс SessionContent

+* CellSelection (1). В данном режиме может выделяться (подсвечиваться) одна ячейка таблицы.
+Ячейка выделяется интерактивно с помощью мыши или клавиатуры (с использованием клавиш управления курсором).
+В данном режиме таблица может получить фокус ввода. В данном режиме таблица генерирует два вида

+
+### Свойство "allow-selection"
+
+По умолчанию вы можете выделить любую ячейку/строку таблицы. Однако часто необходимо запретить 
+выбор определенных элементов. Свойство "selection-mode" (константа SelectionMode) позволяет 
+задать такое правило.
+
+В режиме CellSelection данному свойству присваивается реализация интерфейса
+
+	type TableAllowCellSelection interface {
+		AllowCellSelection(row, column int) bool
+	}
+
+а в режиме RowSelection - реализация интерфейса
+
+	type TableAllowRowSelection interface {

+Функция AllowCellSelection/AllowRowSelection должна возвращать "true" если ячейка/строка
+может быть выделена и "false" если ячейку/строку запрещено выделять.
+
+### События "table-cell-selected" и "table-cell-clicked"
+
+Событие "table-cell-selected" генерируется в режиме CellSelection когда пользователь выделил 
+ячейку таблицы с помощью мыши или клавиатуры.

+
+* RowSelection (2). In this mode, only the entire table row can be selected (highlighted).

+### "allow-selection" property
+
+By default, you can select any cell/row of the table. However, it is often necessary to disable the selection of certain elements. The "selection-mode" property (SelectionMode constant) allows you to set such a rule.
+
+In CellSelection mode, this property is assigned the implementation of the interface
+
+	type TableAllowCellSelection interface {
+		AllowCellSelection(row, column int) bool
+	}
+
+and in RowSelection mode this property is assigned the implementation of the interface
+
+	type TableAllowRowSelection interface {
+		AllowRowSelection(row int) bool
+	}
+
+The AllowCellSelection/AllowRowSelection function must return "true" 
+if the cell/row can be selected and "false" if the cell/row cannot be selected.
+
+### "table-cell-selected" and "table-cell-clicked" events
+
+The "table-cell-selected" event is fired in CellSelection mode when the user has selected 
+a table cell with the mouse or keyboard.
+
+The "table-cell-clicked" event occurs if the user clicks on a table cell (and if it is not selected, 
+the "table-cell-selected" event occurs first) or presses the Enter or Space key.
+
+The main listener for these events has the following format:
+
+	func(TableView, int, int)
+
+where the second argument is the cell row index, the third argument is the column index
+
+You can also use a listener in the following format:
