The height or row has been manually adjusted according to other rows and columns, hiding the text.
The subsequent cells are non-blank cells and the contents of the cell are hiding behind them. The height or width may have been preset which is why the added text won’t make the cell expand accordingly. There could be several reasons and here are a few of them to give you an idea. This is very useful since the worksheet has preset column width and row height and the text entered in the cells may not be displaying completely. AutoFit in Excel is a very quickly applicable feature that fits the text of a cell according to the measurement of the row or column (depending on which one is chosen) the text is in. Auto and fit it doesn’t leave much to the imagination.
