You need to put your pageblocktable in side a outputpanel and when you retreive the data to the table make sure you filter the data based on the picklist selection value. Then use apex:actionSupport to rerender the output panel at the onchage event of the actionSupport.

Okay, Let's think you need to fiter the tax type based on the country you select. then we do someting like this.
In the controller do something like this
  
public String selectedCountry{get;set;}
 
public list<TaxObject> getTaxes(){

// implement the logic that returns the list of selectOptions based on country

if(selectedCountry != null){
  return  this.countryTax(selectedCountry);
}else{
// give error message
}
return null;
} 

public list<SelectOption> getCountries{
// return the country option list
}
In your page do somting like this 
<apex:selectList id="fld1" value="{!selectedCountry}" multiselect="false" size="1" >                                            

    <apex:selectOptions value="{!Countries}"/>       
    <apex:actionSupport event="onselect" action="{!Taxes} rerender="taxPanel
                          " status="SearchStatus immediate="true"/>                                                      
 </apex:selectList>


  
<apex:outputpanel id="taxPanel">
	<apex:dataTable value="{!taxes}" var="tax" id="theTable" rowClasses="odd,even"

                        styleClass="tableClass">

		<apex:facet name="caption">table caption</apex:facet>

		<apex:facet name="header">table header</apex:facet>

		<apex:facet name="footer">table footer</apex:facet>

		<apex:column>
		        <apex:facet name="header">Tax Name</apex:facet>
     			<apex:outputText value="{!tax.name}"/>
		</apex:column>
		<apex:column>

			<apex:facet name="header">Rate</apex:facet>
			<apex:outputText value="{!tax.rate}"/>

		</apex:column>

	</apex:dataTable>
</apex:outputpanel>

To do this you'll need a wrapper class called "TaxObject". Hope you got the idea.
