[SalesForce] visualforce IF syntax

So I need to use an inline if statement in my visualforce page to decide whether or not I need to render an outputText. However I keep hitting a syntax error so I am hoping someone here will catch my (hopefully obvious) mistake.

So there is a field in my custom object that I want to print IF it is populated and not the Id of the contact page I am on. I am also iterating through a list of these objects. So here is what I wrote for an if statement

"{!IF({!relation.First_Contact__c} != null && {!relation.First_Contact__c} != contact.Id), true, false)"

again this is going in the rendered tag of an outputText so the returns are true or false. Also relation is the current custom object from the apex:repeat. Any help is MUCH appreciated.

"{!IF(AND(relation.First_Contact__c != null, relation.First_Contact__c != contact.Id), true, false)}"

Try changing it to this by adding a name attribute to the Apex:param

[SalesForce] rendering the table data through apex code

I would just use a controller property to control the visibility. You also need to use the rerender property for the commandButton. Something like this

VF Page

<apex:commandButton action="{!show}" value="Show" id="cb" rerender="myTable"/>

<apex:pageblocktable rendered="{!showTable}" value="{!Departments}" var="dept_ref" id="myTable">

     <apex:column value="{!dept_ref.Subject__c}"/>
     <apex:column value="{!dept_ref.Syllabus__c}"/>
     <apex:column value="{!dept_ref.Employees__c}" headervalue="Emp count"/>
     <apex:column headervalue="Name" value="{!dept_ref.Name}"/>

</apex:pageblocktable>

APEX

public class myController {

    public boolean showTable      {get;set;}

    public myController() {
         showTable = false;
    }

    public void show() {
         showTable = true;
    } 
}
