Can the width of the textbox which results on adding filterBy attribute to the rich:column be increased

<rich:column filterBy="#{sourcesVar.sourceType}"
filterEvent="onkeyup" sortBy="#{sourcesVar.sourceType}">
 <f:facet name="header">
 <h:outputText value="Source Type" />
 </f:facet>
 <h:outputText styleClass="tableFont"
 value="#{sourcesVar.sourceType}" />
</rich:column>
