How to decrease datatable row height in primefaces - primefaces

Question

I tried to decrease the height of the column by using following syntax:
<p:column style="height:10px;">
and the datatable row height won't decrease; it only increases if I set a bigger size.
Is there a way to make the height smaller than the default/existing one?
This is the exact code, that I'm using:
<c:forEach var="column" items="#{dispoFillingPage.columnListAuftrag}">
<c:choose>
<c:when test="${column.dateColumn}">
<p:column id="#{column.id}" filterStyleClass="#{column.filterStyleClass}" headerText="#{column.title}" visible="#{column.visible}"
width="#{column.width}" filterBy="#{data[column.property]}" sortBy="#{data[column.property]}" field="#{column.property}"
filterFunction="#{standortPage.filterByDate}" filterMatchMode="contains" style="height:10px">
<f:attribute name="rtcCol" value="#{column}" />
<h:outputText value="#{data[column.property]}">
<f:convertDateTime type="date" pattern="yyyy-MM-dd" />
</h:outputText>
</p:column>
</c:when>
<c:otherwise>
<p:column id="#{column.id}" filterStyleClass="#{column.filterStyleClass}" headerText="#{column.title}" field="#{column.property}"
visible="#{column.visible}" width="#{column.width}" filterBy="#{data[column.property]}" sortBy="#{data[column.property]}"
filterMatchMode="contains" style="height:10px;">
<f:attribute name="rtcCol" value="#{column}" />
<h:outputText value="#{data[column.property]}" />
</p:column>
</c:otherwise>
</c:choose>
</c:forEach>
I have to do this, because I have two datatables with 20 rows each and I have to make them fit in the screen, so that they are entirely visible to the user.

I had to decrease the font-style of the datatable in order to decrease also the row height.
<p:datatable style="font-size:8px">
But this way I decrease the entire datatable.
