You can use apex:repeat to create columns dynamically. As per your Scenario a sample code is given below :
Page:
<apex:page controller="communityTest">
<apex:form>
<apex:commandButton value="Add moe 20 columns" action="{!addCol}" reRender="pan"/>
</apex:form>
<apex:outputPanel id="pan">
<table>
<apex:repeat value="{!str}" var="t">
<tr>
<apex:repeat value="{!iterate}">
<td>{!t}</td>
</apex:repeat>
</tr>
</apex:repeat>
</table>
</apex:outputPanel>
</apex:page>
Controller:
public class communityTest
{
public List<String> str{get; set;}
public List<Integer> iterate{get;set;}
public communityTest()
{
str=new List<String>();
iterate=new List<Integer>();
for(Integer i=1;i<=20;i++)
str.add('alok'+i);
for(integer i=1;i<=5;i++)
iterate.add(i);
}
public pagereference addcol()
{
for(integer i=1;i<=20;i++)
{
iterate.add(i);
}
return null;
}
}
