 ==== Tables ====
-TODO!
+We have already introduce how to define tables. Let us now focus on how to manipulate them with the native methods provided by the table object.
+<code>
+>def vowels := ["a", "e", "i", "o", "u"]
+>>["a", "e", "i", "o", "u"]
+>vowels.length
+>>5
+>vowels.at(1)
+>>"a"
+>vowels.atPut(1, "z")
+>>"z"
+>vowels
+>>["z", "e", "i", "o", "u"]
+>vowels.isEmpty()
+>>false
+>[1,2,3].filter: {|e| e != 2 }
+>>[1, 3]
+>[1,2,3].map: { |i| i + 1 }
+>>[2, 3, 4]
+>vowels.select(2,5).implode()
+>>"eio"
+</code>
+Tables also support some useful iterator methods such as:
+<code>
+>def sum:= 0;
+>>0
+>[1,2,3].each: { |i| sum := sum + i }
+>>nil
+>sum
+>>6
+>def sumNnum (@args) {
+  args.inject: 0 into: { |total, next| total + next}
+}
+>><closure:sumNnum>
+>sumNnum(1,2,3)
+>>6
+</code>
