If you place the direct cursor approximately in the middle between the left and the right margin of a page or a table cell, the text you insert will be centred. Similarly, text is right-aligned when the direct cursor is placed on the right margin.
如果直接定位光标所在的位置距页面或表格单元格左、右边缘的距离大致相等，则插入的文字将居中对齐。同样，当直接定位光标位于右边时，文字将右对齐。
