What I'm trying to do is display the content of table using the following code in Lua.
local people = {
{
name = "Fred",
address = "16 Long Street",
phone = "123456"
},
{
name = "Wilma",
address = "16 Long Street",
phone = "123456"
},
{
name = "Barney",
address = "17 Long Street",
phone = "123457"
}
}
for k, v in pairs(people ) do
print(k, v)
end
The output I got is:
1 table: 0x9a2d8b0
2 table: 0x9a2d110
3 table: 0x9a2cb28
To display nested tables you will have to use nested loops.
Also, use ipairs
to iterate through array-like tables, and pairs
to iterate through record-like tables.
local people = {
{
name = "Fred",
address = "16 Long Street",
phone = "123456"
},
{
name = "Wilma",
address = "16 Long Street",
phone = "123456"
},
{
name = "Barney",
address = "17 Long Street",
phone = "123457"
}
}
for index, data in ipairs(people) do
print(index)
for key, value in pairs(data) do
print('\t', key, value)
end
end
Output:
1
phone 123456
name Fred
address 16 Long Street
2
phone 123456
name Wilma
address 16 Long Street
3
phone 123457
name Barney
address 17 Long Street
