I need some help in implementing complex rules in decision table.. 

Following are the two queries that I need to implement in decision table. 
1 ----------- ((UPPER(PRODUCT_TYPE_CODE) IN ('REO', 'TRM')) OR 
       (UPPER(INVESTMENT_GROUP_TYPE) = 'EQUITY' AND 
       deal_ltv_nbi_ext_Debt <= .6)) AND 
       UPPER(PRIMARY_COLLATERAL_TYPE) = 'HOTEL' 

2 --------------(UPPER(INVESTMENT_GROUP_TYPE) = 'EQUITY' OR 
       UPPER(PRODUCT_TYPE_CODE) = 'LES') AND 
       ((UPPER(NNN_LEASE) = 'Y' AND 
       DECODE(ENHANCED_ITV, 
                NULL, 
                DEAL_ITV_NBI_SPP_CURR_MKT_VAL, 
                ENHANCED_ITV) >= .95 AND Core_Property_Type_YN = 'Y') OR 
       (UPPER(NNN_LEASE) = 'Y' AND 
       DECODE(ENHANCED_ITV, 
                NULL, 
                DEAL_ITV_NBI_SPP_CURR_MKT_VAL, 
                ENHANCED_ITV) >= .85 AND Core_Property_Type_YN = 'N')) 

I need to use decision tables only. so do I implement them. I have attached a decsion table in which I have to implement.<a href="http://drools.46999.n3.nabble.com/file/n4017941/LeverageRuleSheet1.xls" target="_top" rel="nofollow" link="external">LeverageRuleSheet1.xls</a>
