public class ForEachTableRowTag
extends javax.servlet.jsp.tagext.TagSupport

This tag is used to create a nicely wrapped HTML table from a list of fields. This is accomplished in two steps:

1) It takes a list of fields, and wraps it into n columns by m rows needed to form an HTML table. The number of columns is determined by the "breakFields" attribute. When one of the breakFields is found in the selected fields list a new column is added.

2) Once the number of rows and columns in the table are determined, the tag enumerates the field names in each tcEntity.

If there are cells in the last column that have no corresponding fields, those cells are padded out with fieldNames set to an empty string.

This tag is the parent tag of the ForEachTableRowField tag. The ForEachTableRowField tag iterates over each field in the current tcEntity or an explicit field list.
