If cells of the table are merged, this separator is not removed, but
it is hidden.
A text table or a text table row provides the separators in a
sequence of TableColumnSeparator s. If the table only
consists of one column, then this sequence is empty.
The real width of a table depends on the environment (page style and
number of text columns at the table's position, alignment, and left and
right margins). For that reason, the table column separator does not
contain metric values for the column widths. The values are relative
to the value of the property TableColumnRelativeSum .
A table provides this property only if all rows have the same structure.
If the table does not provide the property, then it cannot be set using
.
The state of IsVisible and the count of the sequence
must be the same in
as it was in
. Hidden separators cannot be moved
and they cannot be overtaken by visible separators.
