import {Pipe,PipeTransform} from "@angular/core";
@Pipe({
    name: 'tableFilter',pure: false
})

export class PipeTableFilter implements PipeTransform {

    transform(items:any[],args:any):any[] {
        var isSearch = (data:any): boolean => {
            var isAll = false;
            if(typeof data === 'object' ){
                for (var z in data) {
                    if(isAll = isSearch(data[z]) ){
                        break;
                    }
                }
            } else {
                if(typeof args === 'number'){
                    isAll = data === args;
                } else {
                    isAll = data.toString().match( new RegExp(args,'i') );
                }
            }
            return isAll;
        };
        return items.filter(isSearch);
    }

}

<div class="form">
    <div class="form-group row">
        <div class="col-sm-6">
            <div class="input-group">
                <span class="input-group-addon" id="sizing-addon2"><i class="fa fa-search"></i> 全局搜索</span>

</div>
<table class="table table-hover table-striped table-sortable">
    <thead>
    <tr>
        <th *ngFor="let column of columns" [class]="selectedClass(column.variable)" (click)="changeSorting(column.variable)">
            {{column.display}}
        </th>
    </tr>
    </thead>
    <tbody>
    <tr *ngFor="let object of data | tableFilter: searchText | orderBy : convertSorting() | paging: page: pageSize" (click)="selectOneRow(object)" style="cursor: pointer">
        <td *ngFor="let column of columns">
            {{object[column.variable] | format : column.filter}}
        </td>
