效果 

 后端代码 一个用来回显 一个是修改数据

 Resource方法

    @SuppressWarnings("unchecked")
    @RequestMapping(value = "/template/table/{id}", method = {
            RequestMethod.GET }, produces = "application/json;charset=UTF-8")
    @ResponseBody
    @ApiOperation("给在线模版编辑准备的数据")
    public ResponseEntity<RestResponse<List<ImportField>>> getTemplateTableField(
            @ApiParam(required = true, name = "Authorization", value = "jwt凭证") @RequestHeader(value = "Authorization", required = true) String Authorization,
            @PathVariable(value = "id", required = true) String id) throws URISyntaxException, WebException, Exception {
        TableTemplateField result = importFieldService.getTableFieldByTemplateId(id);
        return ResponseEntity.ok().body(RestResponse.getRestResponse(CommonCodeMessageEnum.SUCCESS.getBizCode(),
                CommonCodeMessageEnum.SUCCESS.getMessage(), result));
    }
    
    
    @SuppressWarnings("unchecked")
    @RequestMapping(value = "/template/table/{id}", method = {
            RequestMethod.POST }, produces = "application/json;charset=UTF-8")
    @ResponseBody
    @ApiOperation("编辑在线模版")
    public ResponseEntity<RestResponse<List<ImportField>>> editTemplateTableField(
            @ApiParam(required = true, name = "Authorization", value = "jwt凭证") @RequestHeader(value = "Authorization", required = true) String Authorization,@RequestBody List<String[]> json,
            @PathVariable(value = "id", required = true) String id){
        System.out.println(json.toString());
        importFieldService.editTemplateTableField(json,id);
        return ResponseEntity.ok().body(RestResponse.getRestResponse(CommonCodeMessageEnum.SUCCESS.getBizCode(),
                CommonCodeMessageEnum.SUCCESS.getMessage(), "success"));
    }

 数据格式，类似一个list<<string>>的格式，返回和接收都是这个格式

[
["20080101", 10, 11, 12, 13, true],
["20090101", 20, 11, 14, 13, true],
["20010101", 30, 15, 12, 13, true],
["20010101", 32, 213, 21, 312, true],
["20010201", 32, 213, 21, 312, true],
["20010301", 32, 213, 21, 312, true],
["20010401", 32, 213, 21, 312, true],
["20010501", 32, 213, 21, 312, true],
["20010601", 32, 213, 21, 312, true]
],
