To fully justify text in a table cell in Microsoft Word, follow these steps:

1. Select the cell or cells that you want to justify.
2. Right-click on the selected cell(s) and choose "Table Properties" from the context menu.
3. In the Table Properties dialog box, click on the "Cell" tab.
4. Under "Vertical alignment," select "Top" or "Center" depending on your preference.
5. Under "Text alignment," select "Justified."
6. Click on the "Options" button next to "Text alignment."
7. In the "Justification" section, select "Distribute text evenly between the margins."
8. Click "OK" to close the "Cell Options" dialog box.
9. Click "OK" again to close the "Table Properties" dialog box.

Your text should now be fully justified within the selected cell(s), with both left and right margins aligned. If there are multiple lines of text within a cell, Word will automatically adjust the spacing between words to ensure that each line fits within the same margins.
