docs table: managing identifiers

[johannes-titz]

For now I commented out the third way of specifying ids as I believe it might lead to confusion. If there is a demand for that we can add it again. But I think the abbreviation should be sufficient for most cases.

But I am wondering, what happens with the abbreviation if numbers are used (e.g. as in the multiplication table)?

from complex table template it gives: "49_=" "39=" "5*5=" "23_=" "123_=" as rows identifiers

Are numbers allowed as ids? I thought this creates problems.

[shevandrin]

yes, it does not pass the verification due to numbers at the beginning:

Error: Xml file is not valid.

should i add some prefix at the beginning like r?

[shevandrin]

moreover, all special characters are not allowed to be in identifiers. so I eliminate them as well. now for complex table template: rows identifiers are "row49_" "row39_" "row55_" "row23_" "row123_" cols identifiers are "col27" "col36" "col25" "col6"

this values passed xml verification

[johannes-titz]

So if it is invalid you are adding row/col to the identifier, right?

[shevandrin]

if it strarts with ditigs, col/row is added as prefix. All symbols (except digits, letters and underscore) are removed in any case.

Okay, I added this to the docs.
