Sometimes in Word, the table made in a large and small range, so that when more text input will be automatically wrapped, the table row height will follow. If you want a Word table text line to appear and automatically fit the cell's width, you can use the Fit Text feature of the table.
Select the cells for which you want to adjust the width of the text. Then on the Table menu, click the table Properties ... command, switch to the Cell tab of the dialog box, click the Options ... button to open the Unit Cell dialog box, and select the Fit Text check box below. Determine the exit dialog box in turn.
After you have set up, enter text in these cells, and the text will adjust the character scale and kerning automatically (the font size does not change) to fit the original width of the cell. If the cell height is small and the font is enlarged, the row height of the row of the cell is automatically adjusted with the font size.
