Use numbering and transposing if required.
Numbering of rows and columns can be set up for table area.
To enable numbering for rows and columns, click the 
Numbering button on the Table ribbon tab. If on creating or editing table area, the numbering was not defined, then by default:
Row numbers will be displayed in a new sidehead column before headers. Numbering starts from rows containing data.
Columns numbers will be displayed in a new heading row after headers. Numbering starts from the first sidehead column.
To enable numbering only for rows, select the By Rows checkbox in the Numbering button drop-down menu.
To enable numbering only for columns, select the By Columns checkbox in the Numbering button drop-down menu.
It is available to set up area of numbering layout in the web application. To do this, select the By Rows > Before Header / By Rows > After Header or By Columns> Before Header / By Columns> After Header item in the Numbering drop-down menu.
It is required to set up numbering on creating or editing table area.
Table area can be transposed: to place sidehead dimensions in heading and heading dimensions - in sidehead.
To transpose table area, click the 
Transpose button on the Table ribbon tab.
NOTE. The table area can be transposed on editing.
