Can't editable when data is json data in textarea data type

[grady-xing]

1. when I create bootstrap table with editable function and data-type is textarea
2. my column data is json format data, and I JSON.stringfy the data and load the table, but the column can't show the data normally
   example:
   i. {"name":"apple", "status":{"red":"good", "yellow":"warning"}}
   ii. when load the data, only showing "{", data value is normally, seems only show the content of first quota
   iii. when click the edit, can't load the data-value
