Lua读取CSV文件到table中

创建Lua函数载入CSV文件并保存到表中的函数：

function GetLines(fileName)
        indx = 0
        myLines ={} 
        for line in io.line(string.format("%s%s", "c:/lua_scripts/",filename)) do
                indx = indx + 1
                myLines[indx] = line
        end
        return indx, myLines --returns number of lines and line table
end


function GetValues(myString)
        num = 0
        values = {}
        if myString ~= nil then
                while string.find(myString, ",") ~= nil do
                        i, j =string.find(myString, ",");
                        num =num + 1;
                        values[num] = string.sub(myString, 1, j-1);
                        myString = string.sub(myString, j+1, string.len(myString))
                end
                num = num + 1
                values[num] = myString
        end
        return num, values
end
