Field Detail

state

private Table.State state

Keeps track of the handler state between SAX events.

suppressedStarts

private int suppressedStarts

The number of suppressed element starts.

hardWidth

private boolean hardWidth

Indicates whether the width of the table was established by column markup.

columnCount

private int columnCount

first

private ColumnRange first

The head of the column range list.

last

private ColumnRange last

The tail of the column range list.

currentColRange

private ColumnRange currentColRange

The range under inspection.

previousColRange

private ColumnRange previousColRange
