from entries that haven't changed (normally all tags are removed).
@end defun
@defun tabulated-list-delete-entry
This function deletes the entry at point.
It returns a list @code{(@var{id} @var{cols})}, where @var{id} is the
ID of the deleted entry and @var{cols} is a vector of its column
descriptors. It moves point to the beginning of the current line. It
returns @code{nil} if there is no entry at point.
Note that this function only changes the buffer contents; it does not
alter @code{tabulated-list-entries}.
@end defun
@defun tabulated-list-get-id &optional pos
This @code{defsubst} returns the ID object from
@code{tabulated-list-entries} (if that is a list) or from the list
returned by @code{tabulated-list-entries} (if it is a function). If
omitted or @code{nil}, @var{pos} defaults to point.
@end defun
@defun tabulated-list-get-entry &optional pos
This @code{defsubst} returns the entry object from
@code{tabulated-list-entries} (if that is a list) or from the list
returned by @code{tabulated-list-entries} (if it is a function). This
will be a vector for the ID at @var{pos}. If there is no entry at
@var{pos}, then the function returns @code{nil}.
@end defun
@vindex tabulated-list-use-header-line
@defun tabulated-list-header-overlay-p &optional POS
This @code{defsubst} returns non-nil if there is a fake header at
@var{pos}. A fake header is used if
@code{tabulated-list-use-header-line} is @code{nil} to put the column
names at the beginning of the buffer. If omitted or @code{nil},
@var{pos} defaults to @code{point-min}.
@end defun
@vindex tabulated-list-padding
@defun tabulated-list-put-tag tag &optional advance
This function puts @var{tag} in the padding area of the current line.
The padding area can be empty space at the beginning of the line, the
width of which is governed by @code{tabulated-list-padding}.
@var{tag} should be a string, with a length less than or equal to
@code{tabulated-list-padding}. If @var{advance} is non-nil, this
function advances point by one line.
@end defun
@defun tabulated-list-set-col col desc &optional change-entry-data
This function changes the tabulated list entry at point, setting
@var{col} to @var{desc}. @var{col} is the column number to change, or
the name of the column to change. @var{desc} is the new column
descriptor, which is inserted via @code{tabulated-list-print-col}.
If @var{change-entry-data} is non-nil, this function modifies the
underlying data (usually the column descriptor in the list
@code{tabulated-list-entries}) by setting the column descriptor of the
vector to @code{desc}.
