object中定义的Lua 2d数组使用按引用传递

local array = {}
for i = 1, n do
    array[i] = {}
    for j = 1, m do
        array[i][j] = value
    end
end

function modifyArray(array)
    array[1][1] = "modified"
end

local array = {
    {"value1", "value2"},
    {"value3", "value4"}
}

print("Before modification:")
for i = 1, 2 do
    for j = 1, 2 do
        print(array[i][j])
    end
end

modifyArray(array)

print("After modification:")
for i = 1, 2 do
    for j = 1, 2 do
        print(array[i][j])
    end
end

Before modification:
value1
value2
value3
value4
After modification:
modified
value2
value3
value4
