I'm using richfaces 3.3.0 using extended data table. The table will let me make columns smaller, but not larger than the default width. Once I make the columns smaller, I can not bring them back to their default width. Here's my table:

<h:form id="gridForm">
 <rich:extendedDataTable id="activitiesGrid" value="#{activitiesListingDataModel}" var="row"
 rows="20" width="100%" sortMode="single"
 selectionMode="multi" tableState="#{activitySearchDataProvider.activitiesTableState}">
 <rich:column id="activityNameColumn" sortable="true" label="#{field_activityName}"
 sortBy="#{row.activityName}" width="150px">
 <f:facet name="header">
 <h:outputText value="#{field_activityName}"/>
 </f:facet>
 <h:outputLink value="/activity/#{row.activityId}">
 <h:outputText value="#{row.activityName}"/>
 </h:outputLink>
 </rich:column>
 <rich:column id="activityTypeColumn" sortable="true" label="#{field_activityType}"
 sortBy="#{row.activityTypeName}" width="100px">
 <f:facet name="header">
 <h:outputText value="#{field_activityType}"/>
 </f:facet>
 <h:outputText value="#{row.activityTypeName}"/>
 </rich:column>
 <rich:column id="locationColumn" sortable="true" label="#{field_location}"
 sortBy="#{row.locationName}" width="150px">
 <f:facet name="header">
 <h:outputText value="#{field_location}"/>
 </f:facet>
 <h:outputText value="#{row.locationName}"/>
 </rich:column>
 </rich:extendedDataTable>
 <rich:datascroller id="pageScroller" for="activitiesGrid"
 page="#{activitySearchDataProvider.scrollerPage}"
 align="center" maxPages="10"/>
</h:form>
