Display table titles from nested list shows to much - jsf

Question

I'm writing a blog, and I want to display from database dataTable with 2 columns, in one column I would like to have post title, and in other I want post content, but when I try to implement that in my page, the only result I get is that in post title column is displayed all post titles for every row. I would like to ask you, how could I achieve my goal.
Now i have
title1 title2 ... | content1
title1 title2 ... | content2
etc
but I would like to have
title 1| content1 <br>
title2 | content2 <br>
Here is my index.xhtml code to display dataTable
<h:dataTable value="#{postView.postList}"
var="k"
styleClass="table"
headerClass="tableHeader"
rowClasses="tableContent"
>
<h:column>
<h:dataTable value="#{postView.postList}" var="t">
<h:column>
#{t.title}
</h:column>
</h:dataTable>
</h:column>
<h:column>
#{k.postContent}
</h:column>
</h:dataTable>
Here is my controller
package ManagePost;
import Entities.Post;
import FacadeDAO.PostFacade;
import FacadeDAO.UserFacade;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.view.ViewScoped;
import javax.inject.Inject;
import javax.inject.Named;
#Named
#ViewScoped
public class PostView implements Serializable {
#Inject
private PostFacade postDAO;
private List<Post> postList;
private String title;
private String content;
public PostView() {
}
public List<Post> getPostList() {
return postList;
}
public void setPostList(List<Post> postList) {
this.postList = postList;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
#PostConstruct
public void init() {
postList = postDAO.showAll();
}
public String validate() {
Post post = postDAO.checkIfExist(title);
if (post == null) {
Post newPost = new Post();
newPost.setTitle(title);
newPost.setPostContent(content);
try {
postDAO.add(newPost);
} catch (Exception e) {
e.printStackTrace();
return null;
}
return "loginPage";
} else {
return null;
}
}
}
And the last, PostDao
public List<Post> showAll() {
List<Post> postList = new ArrayList<>();
List<Post> result = getEntityManager().createNamedQuery("Post.findAll", Post.class).getResultList();
postList.addAll(result);
return postList;
}

You are displaying all the titles in an embedded datatable. You should remove the nested datatable tag:
<h:dataTable value="#{postView.postList}"
var="k"
styleClass="table"
headerClass="tableHeader"
rowClasses="tableContent"
>
<h:column>
#{k.title}
</h:column>
<h:column>
#{k.postContent}
</h:column>
</h:dataTable>
