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
