var table_data = '<table class="table table-bordered table-striped">';

table_data += '<tr>';

运行此代码时出现以下错误:
jquery.min.js:4 从源“null”访问“file:///C:/Users/rkuchhadia/Music/Dash/database_backup/iguana.csv”的 XMLHttpRequest 已被 CORS 策略阻止:交叉原始请求仅支持协议方案:http、data、chrome、chrome-extension、https。

如果我们想在 ajax 中加载 CSV 文件,那么我们必须需要服务器??
