Hello, If I understand you, you can see the cell where are you working in? Do you have some rows or columns hide?

To unhide you can click on the up-left corner of the worksheet. It's a rectangle that selects all the rows and columns of the sheet.

When you are selecting all, right click over a column and click in Unhide
Then right click over a row and click Unhide.

I don't know if that answers your question,
