# and the events forwarded to any child widgets

#
# layout = GridLayout
# I am using a grid layout in order to align/resize the table
# to the root widget (the terminal area)
#

# I am enabling the mouseTrack because the table can handle
# the mouse move events and highlight the cells under the cursor

# I am initializing a simple list where any cell is a string representing its position (row,col) inside the list
