如何解决警告文本：DataTables警告：表ID = user_log_list-第0行

Question

我收到此错误消息警告文本：DataTables警告：表ID = user_log_list-请求第0行的未知参数'Date'，但是我的表可以正常工作并且可以正常加载。这是我的代码。我相信这与我在数据表中定义的列数或列数有关。以下是我的VUE组件文件。请告知。

<template>
    <table id="user_log_list" class="table table-stripped table-bordered table-wordbreak">
    </table>
</template>

<script>
    export default {
        name: 'tableLogs',
        props: ['logs'],
        data() {
            return {
                columns: [{
                    title: 'Date'
                }, {
                    title: 'User'
                }, {
                    title: 'Role'
                }, {
                    title: 'Description'
                }],
                rows: [],
                dt_handle: null
            }
        },
        watch: {
            logs(val) {
                let tbl = this;
                tbl.rows = [];

                val.forEach(function(item) {                   
                    let row = [];                   

                    if(item.get_user) {
                        let role = item.get_user.user_type;
                        row.push(formatDate(item.local_created_at));
                        row.push(item.get_user.full_name);
                        row.push((role.charAt(0).toUpperCase() + role.slice(1)).replace('_', ' '));
                        row.push(item.description);
                    }

                    tbl.rows.push(row);
                });

                tbl.dt_handle.clear();
                tbl.dt_handle.rows.add(tbl.rows);
                tbl.dt_handle.draw();
            }
        },
        mounted() {
            let tbl = this;  
            tbl.dt_handle = $(this.$el).DataTable({
                columns: tbl.columns,
                data: tbl.rows,
                searching: true,
                paging: true,
                info: true
            });
        }
    }

    function formatDate(local_created_at) {

        let date = new Date(local_created_at);
        let day = date.getDate();
        let month = date.getMonth() + 1; 
        let year = date.getFullYear();
        let hours = date.getHours();
        let minutes = date.getMinutes();
        let meridian = hours >= 12 ? 'PM' : 'AM';

        hours = hours % 12;
        hours = hours ? hours : 12; 
        minutes = minutes < 10 ? '0'+minutes : minutes;

        let time = hours + ':' + minutes + ' ' + meridian;

        if (day < 10) {
          day = '0' + day;
        } 
        else if (month < 10) {
          month = '0' + month;
        } 

        return date = day + '/' + month + '/' + year + ' ' + time;
    }
