• Initial position of the first cell, on setCellsPosition():

private func setCellsPosition() {
    guard let sections = dataSource?.numberOfSections() else { return }
    for i in 0..<sections {
        guard let rows = dataSource?.numberOfRows(inSection: i) else { return }
        for j in 0..<rows {
            if j == 0 {
                cells[j].position.y = self.tableFrame.height * 0.4
            } else {
                cells[j].position.y = self.previousCellPosition - self.rowHeight
            }
            self.previousCellPosition = cells[j].position.y
        }
    }
}
