不同模块文件中相同变量名总是返回最后一个的问题

你提供的示例模块的代码没有向返回的表中添加任何内容。

这将导致Chapter成为全局变量，由第一个模块创建，然后由第二个模块更改。

为了纠正这个问题，应该这样编写这些模块：

modOne:

local modOne = {
    Chapter = {
        [1] = {
            chapNum = 1,
            [1] = "This is the first verse of the modOne",
            [2] = "This is the second verse of the modOne",
        },
        [2] = {
            chapNum = 2,
            [1] = "This is the third verse of the modOne",
            [2] = "This is the fourth verse of the modOne",
        }
    }
}
return modOne

modTwo:

local modTwo = {
    Chapter = {
        [1] = {
            chapNum = 1,
            [1] = "This is the first verse of the modTwo",
            [2] = "This is the second verse of the modTwo",
        },
        [2] = {
            chapNum = 2,
            [1] = "This is the third verse of the modTwo",
            [2] = "This is the fourth verse of the modTwo",
        }
    }
}
return modTwo

主代码：

oneModule = require('modOne')
twoModule = require('modTwo')

for i = 1, #oneModule.Chapter do
    for j = 1, #oneModule.Chapter[i] do
        print(oneModule.Chapter[i][j])
    end
end
for i = 1, #twoModule.Chapter do
    for j = 1, #twoModule.Chapter[i] do
        print(twoModule.Chapter[i][j])
    end
end

您也可以简单地确保在定义模块中的Chapter和在模块中使用它的每个地方时均使用modOne.Chapter。
