Nesting Tables
Table cells marked with the AsciiDoc table style (a) support nested tables in addition to normal block content.
To distinguish the inner table from the enclosing one, you need to use !=== as the table delimiter and a cell separator that differs from that used for the enclosing table.
The default cell separator for a nested table is !, though you can choose another character by defining the separator attribute on the table.
| Although nested tables are not technically valid in DocBook 5.0, the DocBook toolchain processes them anyway. |
The following example contains a nested table in the last cell. Notice the nested table has its own format, independent of that of the outer table:
[cols="1,2a"]
|===
| Col 1 | Col 2
| Cell 1.1
| Cell 1.2
| Cell 2.1
| Cell 2.2
[cols="2,1"]
!===
! Col1 ! Col2
! C11
! C12
!===
|===| Col 1 | Col 2 | ||||
|---|---|---|---|---|---|
Cell 1.1 |
Cell 1.2 |
||||
Cell 2.1 |
Cell 2.2
|
We recommend using nested tables sparingly. There’s usually a better way to present the information.
