Hi ,
I tried the code u have shared and it is updating the height and width of the cell, below is my code (Liferay 7.3.4 GA5)
<%
int userCount = UserLocalServiceUtil.getUsersCount();
%>
<liferay-ui:search-container total="<%=userCount %>" delta="5" rowchecker="<%=new RowChecker(renderResponse) %>">
<liferay-ui:search-container-results results="<%=UserLocalServiceUtil.getUsers(searchContainer.getStart(), searchContainer.getEnd())%>" />
<liferay-ui:search-container-row cssclass="search-container" classname="com.liferay.portal.kernel.model.User" modelvar="userTemp" escapedmodel="<%= true %>" indexvar="indexNumber" rowvar="curRow" keyproperty="userId">
<liferay-ui:search-container-column-text property="userId" name="User Id" />
<liferay-ui:search-container-column-text property="firstName" name="First Name" />
<liferay-ui:search-container-column-text property="lastName" name="Last Name" />
</liferay-ui:search-container-row>
<liferay-ui:search-iterator />
</liferay-ui:search-container>
<style>
.search-container td{
height: 50px;width: 40px ;
}
</style>
You can try adding !important also , if in case above codes doesn't work for you .
<style>
.search-container td{
height: 50px !important;
width: 40px !important;
}
</style>
