We often use C tags to traverse the required data, for ease of use, the Varstatus property allows us to implement some of the functions related to the number of rows, such as: odd lines, even line differences, the last line of special processing and so on. The general parameters of the Varstatus attribute are summarized in the first:

${status.index} output line number, starting from 0. ${status.count} output line number, starting from 1. ${status.current} The item (in the collection) of the current iteration ${status.first} Determines whether the current item is the first item in the collection, the return value is true, or false${status.last} determines whether the current item is the last item in the collection. The return value is true or falsebegin, end, step, respectively: Starting sequence, ending ordinal, jumping pace. such as: <c:foreach begin= ' 1 ' end= ' 5 ' step= ' 2 ' items= ' ${list} ' var= ' item ' > means: Operation List collection sinks in the data, not one by one cycle, but per 2 values. This is the 1th, 3, and 5 data in the Operations collection.
