Import CSV results in one-column and shows ";"

Drupal on denwer. Added a tablefield to a standart article content type. When importing a CSV (saved from excell table) the error comes:
"Notice: Undefined index: format in ckeditor_pre_render_text_format() (line 244 of Z:\home\test\www\sites\all\modules\ckeditor\ckeditor.module)."
and information in table shown as "1;11;;11;;44;" instead of being a table.
How to fix it? What is the reason?
Unmarked CKeditor in modules - first error vanished, but the main issue stayed - the table is still as a text in rows.
