KEY
TYPE
VALUE
TBorderStyle
name or
array
(Optional; inheritable; PDF 1.5)
The style of the border drawn on each edge of
a table cell. Possible values are the same as those specified for
BorderStyle
(see Table 10.30). If both
TBorderStyle
and
BorderStyle
apply to a given table
cell,
BorderStyle
supersedes
TBorderStyle
. Default value:
None
.
(Optional; inheritable; PDF 1.5)
Specifies an offset to account for the separa-
tion between the table cell’s content rectangle and the surrounding border
(see “Content and Allocation Rectangles” on page 930). If both
TPadding
and
Padding
apply to a given table cell,
Padding
supersedes
TPadding
. A positive
value enlarges the background area; a negative value trims it, possibly allow-
ing the border to overlap the element’s text or graphic. The value is either a
single number representing the width of the padding, in default user space
units, that applies to all four edges of the table cell or a 4-entry array repre-
senting the padding width for the before edge, after edge, start edge, and end
edge, respectively, of the content rectangle. Default value: 0.
TPadding
integer or
array
Layout Attributes for ILSEs
The attributes described in Table 10.32 apply to inline-level structure elements
(ILSEs). They may also be specified for a block-level element (BLSE) and apply to
any content items that are its immediate children.

KEY
TYPE
VALUE
BaselineShift
number
(Optional; not inheritable)
The distance, in default user space units, by
which the element’s baseline is shifted relative to that of its parent element.
The shift direction is the opposite of the block-progression direction spec-
ified by the prevailing
WritingMode
attribute (see “General Layout Attri-
before edge and negative values toward the after edge of the reference area
(upward and downward, respectively, in Western writing systems). Default
value: 0.
The shifted element might be a superscript, a subscript, or an inline graph-
ic. The shift applies to the element, its content, and all of its descendants.
Any further baseline shift applied to a child of this element is measured
relative to the shifted baseline of this (parent) element.
