  min: [2, 2], // min. table size 2x2
  max: [4, 4], // max. table size 4x4
  fill: 0      // fill new rows/ chars with 0
})
// table.table = [[1,2],[3,4]]

table.removeRow() // tries to remove row at end
//> false - min. rows exceeded
table.removeColumn() // tries to remove column at end
//> false - min. columns exceeded

table.addRow() // adds row at end
//> true
// table.table = [[1,2],[3,4],[0,0]]
table.addColumn()   // adds column at end
//> true
// table.table = [[1,2,0],[3,4,0],[0,0,0]]
table.addRow(0, 100)
//> true
// table.table = [[100,100,100],[1,2,0],[3,4,0],[0,0,0]]
table.addColumn(1, 20)
//> true
// table.table = [[100,20,100,100],[1,20,2,0],[3,20,4,0],[0,20,0,0]]
table.addColumn()

// table.table = [[100,20,100],[1,20,0],[3,20,0],[0,20,0]]
table.removeRow(2)
//> true
// table.table = [[100,20,100],[1,20,0],[0,20,0]]
