Layui table表格操作列，按钮过多时展开点击失效问题解决方法

// 缓存当前操作的是哪个表格的哪个tr的哪个td
$(document).off('mousedown','.layui-table-grid-down')
.on('mousedown','.layui-table-grid-down',function(event){
	table._tableTrCurr = $(this).closest('td');
});

$(document).off('click','.layui-table-tips-main [lay-event]')
.on('click','.layui-table-tips-main [lay-event]',function(event){
 var elem = $(this);
 var tableTrCurr = table._tableTrCurr;
 if(!tableTrCurr){
 return;
 }
 var layerIndex = elem.closest('.layui-table-tips').attr('times');
 // 关闭当前这个显示更多的tip
 layer.close(layerIndex);
 table._tableTrCurr.find('[lay-event="' + elem.attr('lay-event') + '"]').first().click();
});

在layui2.4.5版本中,将上面代码放进layui.use（）函数里面即可
