Wrapper Class:-

global class wrapDelete {        
    public wrapDelete (){}
    
    Global class wrapDeleteInner{        
        global Case CaseObj{get;set;}
        global Lead LeadObj{get;set;}
        
        global wrapDeleteInner(){}
        
        }
        
        global List<wrapDeleteInner> getDeleteList(){            
            List<wrapDeleteInner> wrap = new List<wrapDeleteInner>();
            
            for (Lead l:[Select id,name from Lead limit 5]){
                wrapDeleteInner wr = new wrapDeleteInner();
                wr.LeadObj = l;
                wrap.add(wr);                               
            } 
            
            for (Case C:[Select id,CaseNumber from Case limit 5]){
                wrapDeleteInner wr = new wrapDeleteInner();
                wr.CaseObj = C;
                wrap.add(wr);                               
            }            
            return wrap;                                
        }        
    
}

Visualforce Page:-

<apex:page Controller="wrapDelete">
    <apex:pageBlock title="Lead and Case Table">
        <apex:pageblockTable value="{!DeleteList}" var="item">
            <apex:column value="{!item.LeadObj.name}"/>            
            <apex:column value="{!item.CaseObj.CaseNumber}"/>           
        </apex:PageblockTable>                       
    </apex:pageBlock>
