I need to include a table on my visualforce page and query the data from the custom objects already developed in Salesforce application. while browsing over the internet, i came thru some controller class example and need to write a visualforce page for that.. I tailored the class shown below as per my requirements, but couldn't write code for the page..Could someone help me in this issue..? total columns to display would be 10. 

Its prime urgent and I'm running out of time.. 

public class OpportunityLineItemsController {
    Public List<OpportunityLineItems> LineItems = new List<OpportunityLineItems>();

    public List<OpportunityLineItems> getLineItems() {
        LineItems =[select id from OpportunityLineItem limit 10];
        return LineItems;
    }

Secondly:

When i save the below page, it thorws an error.

Save Error:Unknown property 'Billing_Close__cStandardController.Save'..why is this occuring..?

<apex:page standardController="Billing_Close__c" showheader="false" sidebar="false">

<apex:sectionHeader title="Billing Close Edit" subtitle="New Billing Close" />

<apex:form>
