Insert a table into the text box and set the width of the table to the desired width. 3. Select the first line and the last line, find the "Horizontal Alignment" option on the "Properties" panel, and set it to "Center". 4. Repeat step 3 to perform the same operation on the second and third lines. 5. Finally, click "OK" on the "Properties" panel. In this way, the table in the text box will be automatically centered.If you need to modify the width of the table or adjust other properties, you can enter the Properties panel again to set.
If nothing unexpected happens, you can display the hidden characters. The shortcut key is ctrl+alt+i, and you will see a paragraph symbol behind each line of words, indicating that they are independent paragraphs, not a whole.Delete these paragraph symbols to align the left and right.
