Hi, Not sure if the below code helps.

Apex-Class: 
public class myTaskClassComponent {
    public List<Task> ListTasks {get; set;}
    public void fetchRecords(){
        ListTasks = [SELECT DB_Activity_Type__c,ActivityDate,Priority,Status,Subject,TaskSubtype FROM Task ORDER BY Priority DESC, ActivityDate DESC];
    }
}

VF-Page: 
<apex:page controller="myTaskClassComponent">
    <apex:form id="VF_AcctsForm">
        <apex:pageBlock>
            <apex:commandButton value="List Records" action="{!fetchRecords}" rerender="VF_AcctsFormPageBlockTbl"/>
            <apex:pageBlockTable value="{!ListTasks}" var="w" id="VF_AcctsFormPageBlockTbl">                
                <apex:column headervalue="Activity Type" id="VF_AcctsFormPageBlockTblhdr2">
                    <apex:outputtext value="{!w.DB_Activity_Type__c}" id="VF_AcctsForminputField2"/>
                </apex:column>
                <apex:column headervalue="Due date" id="VF_AcctsFormPageBlockTblhdr3">
                    <apex:outputText value="{0, date, d-MMM-yyyy}" id="VF_AcctsForminputField3">
                        <apex:param value="{!w.ActivityDate}" />
                    </apex:outputText>
                </apex:column>
                <apex:column headerValue="Priority" id="VF_AcctsFormPageBlockTblhdr4">
                    <apex:outputtext value="{!w.Priority}" id="VF_AcctsForminputField4"/>
                </apex:column>
                <apex:column headerValue="Status" id="VF_AcctsFormPageBlockTblhdr5">
                    <apex:outputtext value="{!w.Status}" id="VF_AcctsForminputField5"/>
                </apex:column>
                <apex:column headerValue="Subject" id="VF_AcctsFormPageBlockTblhdr6">
                    <apex:outputtext value="{!w.Subject}" id="VF_AcctsForminputField6"/>
                </apex:column>
                <apex:column headerValue="Task Sub-Type" id="VF_AcctsFormPageBlockTblhdr7">
                    <apex:outputtext value="{!w.TaskSubtype}" id="VF_AcctsForminputField7"/>
                </apex:column>
            </apex:pageBlockTable>
        </apex:pageBlock>
    </apex:form>
</apex:page>

hi,
just one more question.

How can i add fields of a custom object in the same table based on whatid of these tasks.????
thanks, Amit Yadav

Hi, If you fetch the whatId from another query then include it in the query before "ORDER BY".

Say you have customer Object "Student__c" which has field "Student_ID", then,

Case-I 
public class myTaskClassComponent {
    public List<Task> ListTasks {get; set;}
    public void fetchRecords() {
        String whatID = '90999XXXXXX'; // for example
        ListTasks = [SELECT DB_Activity_Type__c,ActivityDate,Priority,Status,Subject,TaskSubtype FROM Task where whatId =: whatID ORDER BY Priority DESC, ActivityDate DESC];
    }
}
Case-II 
public class myTaskClassComponent {
    public List<Task> ListTasks {get; set;}
    public List<Student__c> ListStudents {get; set;}
    public void fetchRecords(){
        for(Student__c LstRecords: ListStudents) {
              ListTasks = [SELECT DB_Activity_Type__c,ActivityDate,Priority,Status,Subject,TaskSubtype FROM Task where whatId=: LstRecords.whatId ORDER BY Priority DESC, ActivityDate DESC];
        }
    }
}
Hope the above idea helps.
