I created a table on the first page of my document and somehow there appeared a 2nd page after this. I need to delete this second blank page but am unable to do so. Can you help me?

After a table, there must always be another paragraph. If there's no text after the table, there'll be an empty paragraph there. What you can do in such cases is to ensure the trailing paragraph:
a) is formatted with 0 before/after spacing; and
b) has its font size set to 1pt and formatted as hidden
That should resolve the issue.

not sure I follow, thank you so much for your help. Could you explain the O/spacing and decreasing font size down to 1 again?

The space before/after is set via the 'Paragraph' panel's dropdown on the ribbon's Home tab (or Alt-H, P, G, I, Alt-B for the Before box) - and its 0 not O.
The font size is controlled via the font-size combobox, right next to the font name on the Font panel, also on the ribbon's Home tab (or Alt-H, F, N, Alt-S, 1).
