/* $DOC$
* $FUNCNAME$
* TB2Html()
*
* $ONELINER$
* Generates HTML tables (documents) from TBrowse objects
*
* $SYNTAX$
* TB2Html( <oTBrowse>, <cHtmlFile>, [<cTitle>] ) -> lSuccess
*
* $ARGUMENTS$
* <oTbrowse> is a TBrowse object
* <cHtmlFile> is name of HTML (.HTM) document to generate
* <cTitle> is optional table title
*
* $RETURNS$
* Returns true (.T.) if successfull, false (.F.) in case of error.
*
* $DESCRIPTION$
* TB2Html() generates HTML tables based on TBrowse objects which
* is passed as argument (along with target HTML file name and
* optional title). It respects custom skip blocks, so it can be
* used for converting arrays as well as standard DBF files.
* TB2Html evaluates field data the same way TBrowse do
* (evaluating the field code block) so works with calculated
* columns without any problems. It also respects any additional
* column formatting (TBColumn:picture) and replace empty values
* with non-breaking spaces. Table header is automatically
* generated from TBColumn:Heading with support for multi-line
* headers.
*
* $EXAMPLES$
*
* // this is sample part of standard main TBrowse loop
* do while .t.
* oTB:forceStable()
* nKey := Inkey()
* do case
* // standard key (up,down,etc.) processing goes here
* case nKey == K_ALT_H
* if Alert("Generate HTML table?", {"Yes","No"})==1
*
* TB2Html (oTB, "Table.htm", "Sample table")
*
* endif
* end case
* end do
*
* $END$
