|

* eg. the column-headers in the eTemplate-editor are templates itself,
|
|
* to show the column-name in the header you can not use $col as it will
|
|
* be constant as it is always the same col in the header-template,

|

|
|
* Autorepeat is important to allow a variable numer of rows or cols, eg. for a list.
|
|
* The eTemplate has only one (have to be the last) row or column, which gets
|
|
* automaticaly repeated as long as content is availible. To check this the content
|
|
* has to be in an sub-array of content. The index / subscript into content is
|
|
* determined by the content of size for templates or name for regular fields.
|
|
* An autorepeat is defined by an index which contains variables to expand.
|
|
* (vor variable expansion in names see expand_names). Usually I use the keys
|
|
* $row: 0, 1, 2, 3, ... for only rows, $col: '@', 'A', 'B', 'C', ... for only cols or
|
|
* $col$row: '@0','A0',... '@1','A1','B1',... '@2','A2','B2',... for both rows and cells.
|
|
* In general everything expand_names can generate is ok - see there.
