DESCRIPTION
This file defines KWord tables. A table is a KWFrameSet, thus allowing its
internal structure to be invisible to the rest of kword. This is useful
since the internal structure of a table is itself a series of KWFrameSets
(one for each cell).

/**
All the TableIterator templates are the same, except for the pre-increment
operator (operator++). There is a specialised version of this
operator method for each iterator type:
VISIT_GRID: This iterator visits each grid position once, ie every
location in the m_rowArray rows. When some cells are joined, this
iterator will visit those cells more than once.
VISIT_CELL: This iterator visits each cell in the table once, whether
or not some of the cells are joined. If you want to visit all the cells
fast and perform some read-only operation, this is the one to use.
CHECKED: Also visits each cell once, but has some other benefits. Slower.
Note that all the iterators have restrictions on the state that the
table data structures are in before and while they are being used.
This includes m_rowArray, the Rows and Cells but not m_colPositions and
m_rowPositions, as they are not used during the traversal.
The conditions include:
<UL>
<LI>( A ) All positions in m_rowArray must be occupied by a valid cell, ie must
not be null.</LI>
<LI>( B ) The Cell instance variables (m_row, m_rows, etc) must correctly
correspond to where the cells are in m_rowArray.</LI>
<LI>( C ) The m_rows and m_cols instance variables of the table are also correct.</LI>
</UL>
Taken together, these conditions are pretty much equivalent to the
validate() function passing. These conditions may not hold in the middle
of a method when table data structures are being manipulated.
This table shows what conditions are necessary for each type of iterator:
<TABLE>
<TR><TD> </TD><TD>A</TD><TD>B</TD><TD>C</TD></TR>
<TR><TD>TableIterator\<VISIT_GRID\></TD><TD>x</TD><TD> </TD><TD>x</TD></TR>
<TR><TD>TableIterator\<VISIT_CELL\></TD><TD>x</TD><TD>x</TD><TD>x</TD></TR>
<TR><TD>TableIterator\<CHECKED\> </TD><TD> </TD><TD> </TD><TD>x</TD></TR>
<TR><TD>MarkedIterator </TD><TD>x</TD><TD> </TD><TD>x</TD></TR>
</TABLE>
The only iterator that can be used when there are null positions in the
table is the checked iterator.
Note that both the Checked and Marked Iterators traverse the table twice,
once to clear the m_marked members in the cells (done in constructor) and
then again to do the actual traversal. Because they use m_marked, only one
of these iterators can be used at once.
Don't use these classes directly in code, use the provided typedefs. That
makes it easy to do more crazy template stuff later on. :-) Templates
are used here rather than inheritance to avoid virtual call overhead.
