How to extract deleted count values from the below csv data and add them as a separate field?

This looks awfully like https://community.splunk.com/t5/Splunk-Search/How-to-extract-a-value-from-the-message-using-rex-comm..., but the data fragment is somewhat more straight-forward.  Let me give it a try using a similar method. (BTW, the data frame is not CSV, but a JSON object.)

You never indicated whether the cited data is the complete raw event.  I will assume that it is in the following.  I also assume that you are using Splunk 8 or higher so you can take advantage of JSON functions.  Further more, I assume that you want to list each deleted_count with the corresponding table_name.  An additional assumption used in both is that each message contains < 9999 table names.

| eval message = replace(_raw, "Dataframe row : ", "")
| spath input=message
| eval json0 = json_object()
| foreach c0.*
    [eval json0 = json_set(json0, printf("%04d", <<MATCHSTR>>), '<<FIELD>>')]
| eval json1 = json_object()
| foreach c1.*
    [eval json1 = json_set(json1, printf("%04d", <<MATCHSTR>>), '<<FIELD>>')]
| eval json2 = json_object()
| foreach c2.*
    [eval json2 = json_set(json2, printf("%04d", <<MATCHSTR>>), '<<FIELD>>')]
| eval json3 = json_object()
| foreach c3.*
    [eval json3 = json_set(json3, printf("%04d", <<MATCHSTR>>), '<<FIELD>>')]
| fields - _* c*.* message
| eval frag = mvrange(1, mvcount(json_array_to_mv(json_keys(json0))))
| eval frag = mvmap(frag, printf("%04d", frag))
| eval jsontable = mvmap(frag, json_object(json_extract(json0, "0000"), json_extract(json0, frag), json_extract(json1, "0000"), json_extract(json1, frag), json_extract(json2, "0000"), json_extract(json2, frag), json_extract(json3, "0000"), json_extract(json3, frag)))
| mvexpand jsontable
| foreach table_name deleted_count load_date redelivered_count
    [ eval "<<FIELD>>" = json_extract(jsontable, "<<FIELD>>")]
| table table_name deleted_count redelivered_count load_date

Your sample data should give
