Jquery Datatable的问题fnAdjustColumnSizing

Question

我在调用fnAdjustColumnSizing函数时遇到＆＃34; TypeError：settings is undefined＆＃34; 问题。

目前我正在使用DataTables 1.10.15版本

$('#myDataTable').dataTable().fnAdjustColumnSizing();

或

var oTable = $('#myDataTable').dataTable();
oTable.fnAdjustColumnSizing();

给出同样的错误

api.settings（）的控制台日志值

Answer 1

api.settings()返回一个对象而不是一个数组。需要删除[0]才能获取设置对象。
