Typically, double underlining appears in the figure at the bottom of a table column in an invoice or a financial statement and indicates the end of a specific accounting procedure. ### Grand Total For example, an invoice showing sold line items would use the double underlining under the grand total for all line items including taxes: ![Invoice template](https://s1-www.textcontrol.com/assets/dist/blog/2023/03/02/a/assets/invoice1.webp "Invoice template") Single underlining in accounting is generally utilized to indicate a subtotal. In the invoice example, the single underlining would be applied to the subtotal before taxes. In newer invoices, typically other formatting options such as bolding or frames are used to indicate the grand total. But the traditional accounting double underlining is still often used in financial statements. ### Tab Stops and Font Underlining To setup an invoice template in TX Text Control, a combination of table cell borders and font underlining can be used to realize the double underlining. ![Invoice template](https://s1-www.textcontrol.com/assets/dist/blog/2023/03/02/a/assets/invoice2.webp "Invoice template") ### Setup Formatting In the above screenshot, you can see the template that uses a combination of tab stops and font underlining in the grand total table cell. In order to create such a formatting, set the input position inside the table cell and remove all existing tab positions. This can be done by clicking and holding the tab position in the horizontal ruler bar to drag it of the ruler bar area: ![Invoice template](https://s1-www.textcontrol.com/assets/dist/blog/2023/03/02/a/assets/invoice3.webp "Invoice template") Then choose *Doubled* from the *Underline* option in the *Font* ribbon group: ![Invoice template](https://s1-www.textcontrol.com/assets/dist/blog/2023/03/02/a/assets/invoice4.webp "Invoice template") Select a right aligned tab from the ruler bar and insert this tab position at the cell location: ![Invoice template](https://s1-www.textcontrol.com/assets/dist/blog/2023/03/02/a/assets/invoice5.webp "Invoice template") As the last step, insert a tab position into the cell by pressing CTRL+TAB and insert text or a merge field after it: ![Invoice template](https://s1-www.textcontrol.com/assets/dist/blog/2023/03/02/a/assets/invoice6.webp "Invoice template") As a result, the complete table cell will be formatted with double underlining to indicate the grand total at the end of the calculation. --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
