dolphindb怎么看一个表一共占用了多少磁盘空间？
我创建一个表，并写入了数据库，代码如下：
db=database("dfs://db1",VALUE,1 2 3)
timestamp = [09:34:07,09:36:42,09:36:51,09:36:59,09:32:47,09:35:26,09:34:16,09:34:26,09:38:12]
sym = `C`MS`MS`MS`IBM`IBM`C`C`C
price= 49.6 29.46 29.52 30.02 174.97 175.23 50.76 50.32 51.29
qty = 2200 1900 2100 3200 6800 5400 1300 2500 8800
t = table(timestamp, sym, qty, price)
dt=db.createTable(t,`dt).append!(t)怎么看这个表dt一共占用了多少磁盘空间？
