Hi Alexandra,
if you have that one text frame after import that is showing overset since there are so many table rows left, just do the following:
1. Switch your tool to the Selection tool, the "Black Arrow Tool".
2. Select the text frame.
3. Click the outport of the text frame that is showing the red plus for overset text.
That should load the rest of the table to your cursor.
4. The text frame is still selected; now remove the text frame by using the Delete key on your keyboard.
Now all the rows of your placed table is in your text cursor.
5. Hold down the Shift key and place the text inside the page margins by clicking the loaded cursor.
That should flow the whole table to your document.
Regards,
Uwe
