1. First, adjust the margins: by adjusting the margins, the table can be centered or aligned to the left. In Word processing software (such as Word), select the page layout or page setup option, and adjust the left and right margins to an appropriate size so that the table is centered or left.

2. Secondly, adjust the width of the table: If the table is still to the right, you can try to adjust the width of the table. Insert or resize cells around the table to make the whole table wider, so that the content is centered or left.

3. Finally, use the table alignment tool: You can find the table alignment tool in the toolbar of word processing software. Align the table contents to the appropriate position by selecting the whole table or the contents in the table, clicking the Align button, and selecting options such as Align Left or Align Center.
