[support] blocks do not display

[Roger]

Apologies for double post, I sent on the wrong email address.

Hello
In the database tables for a drupal 7 install which table contains the 
content types please.

I'm experimenting with installing only certain tables in a vanilla 
install because there are some in the database that I do not want like 
workbench, og, cache, comment, backup_migrate, etc.

I need to learn panels and just need the table structures and data from 
the site. og and workbench do not play well with panels.

Ive installed
block -all
contact
content_access
ctools_access_ruleset
ctools_css_cache
date_format - all
field_config
field_data_field
file - all
node
node_access
node_type
relation - all of them
role - all
rules - all
users - all
taxonomy - all
views_view
views_display

I don't know what the registry table is. Don't know what else I should 
install.
Problem is that none of our content types display in the <add content>. 
content, Taxonomy, rules, views all display as they should but there is 
no blocks.

Can someone please advise me on what table is needed for blocks.
thanks in advance.
Roger
