</apex:page>
apex class->
public class class2
{
List<Account> a= [select Type from Account];
public List<Account> getacc()
{
return a;
}
}
Vf page->
<apex:page controller="class2">
<apex:pageBlock title="List of Accounts">
<apex:pageBlockTable value="{!acc}" var="a">
<apex:column value="{a.Name}"/>
<apex:column value="{a.Type}"/>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:page>
May I suggest you need to add an " ! "mark in all values
<apex:column value="{!a.Name}"/> <apex:column value="{!a.Type}"/>Hope it will be helpful.
Please mark it as best answer if the information is informative.so that question is removed from an unanswered question and appear as a proper solution.
Thanks

Rahul is right, but the exclaimation mark needs to be inside the curly bracket.
<apex:column value="{!a.Name}"/> <apex:column value="{!a.Type}"/>Regards
