请教一个问题，dict值可以是table吗？我这样写：
orders=select TradeChannel,Order,SecID,Market,Side,Price,Volume,OrderType,TimeStamp,0 as DealVolume,0.0 as VWAP, 0.0 as DealValue from tt where SecID='2142.0'
historyDict = dict(STRING, ANY)
historyDict.dictUpdate!(function=append!, keys=orders.SecID, parameters=orders, initFunc=x->table(100:0,x.schema().colDefs.name, x.schema().colDefs.typeString).append!(x))
执行时报错"The input for schema function must be a table or a database."
