layui.table.cache.tablename

当一个页面里存在多个table表格时，加载页面通过以下方式获取表格数据：

var tableIns = table.render({
    elem: '#purchaseList',
    url: ctx + '/purchase/list',
    height: "full-125",
    page: true,
    limits: [10, 15, 20, 25],
    id: "purchaseListTable",
    cols: [[
        {field: "id", title: '编号', fixed: "true", width: 80},
        {field: 'purchaseNumber', title: '采购单号', minWidth: 50, align: "center"},
        {field: 'purchaseDate', title: '日期', minWidth: 50, align: "center"},
        {field: 'supplierName', title: '供应商', minWidth: 100, align: 'center'},
        {field: 'amountPayable', title: '金额', minWidth: 100, align: 'center'},
        {field: 'userName', title: '操作员', minWidth: 100, align: 'center'},
        {field: 'remarks', title: '备注', minWidth: 100, align: 'center'},
        {title: '操作', minWidth: 150, templet: '#purchaseListBar', fixed: "right", align: "center"}
    ]]
});

var tableIns02 = table.render({
    elem: '#purchaseListGoods',
    url: ctx + '/purchaseListGoods/list',
    height: "full-125",
    page: true,
    limits: [10, 15, 20, 25],
    id: "purchaseListGoodsTable",
    cols: [[
        {field: 'code', title: '药品编码', minWidth: 50, align: "center"},
        {field: 'name', title: '药品名称', minWidth: 50, align: "center"},
        {field: 'model', title: '规格', minWidth: 100, align: 'center'},
        {field: 'price', title: '单价', minWidth: 80, align: 'center'},
        {field: 'num', title: '数量', minWidth: 70, align: 'center'},
        {field: 'unit', title: '剂型', minWidth: 100, align: 'center'},
        {field: 'total', title: '总金额', minWidth: 80, align: 'center'},
        {title: '操作', minWidth: 70, templet: '#purchaseListGoodsBar', fixed: "right", align: "center"}
    ]]
});


可以通过layui.table.cache.【tablename】分别获取表格的数据（数据分页时，是当页还是全部还在验证）；tablename为上面代码标红部分
