Lua用table模拟二维数组

 local array = {};
 local row1 = {, , , , }
 local row2 = {, , , , }
 local row3 = {"I", "love", "lua"}
 array[] = row1;
 array[] = row2;
 array[] = row3
 print("length = ", #array);
 for i = , #array do
     for j = , #array[i] do
         print(array[i][j])
     end
 end

 function Create2DArray(row, col)
     local array2D = {}
     for i = , row do
         array2D[i] = {}
         for j = , col do
             array2D[i][j] =
         end
     end
     return array2D
 end

 function Print2DArray(array)
   local  str = ""
     for i = , #array do
         for j = , #array[i] do
             str = table.concat(array[i], " ")
         end
         print(str)
     end
 end
