It is no：Export { current line number, current line number }
(5) go to (7)
(6) whether rangeStart is more than or equal to 0
It is：Continue
It is no：RangeStart is current line number
(7) i increases 1, goes to (1)
(8) terminate
Wardrobe (or row head), also referred to as header line or fixed row, it is the line range with title function.Wardrobe are in form
It is the key factor for needing to consider in printing.In self-defined paging model, the rope of the index set and page break segmentation of wardrobe
Draw set by the processing such as union, sequence, be then converted to the form of scope, that is, complete the structure of self-defined paging model.Example
If the index ranges of a table sample wardrobe is 0 to 4, if the segmentation scope of page break is 0 to 21, then the result of conversion is exactly
{0,21}；If the segmentation scope of page break is 22 to 47, then the result of conversion is exactly { 0,4 } and { 22,47 }.
3rd, the dynamic page adjustment of data state：
Self-defined paging model stores every page line range to be printed and row scope.But, due to depositing for dynamic area
, the data state and design state of form, ranks quantity is often different, if there is dynamic area in table sample, and dynamic area exists
Data state is expanded to after some rows, and the ranks scope stored in paging model cannot directly bring calculating print range, therefore
A kind of dynamic adjusting method in data state is needed, it can be moved according to the spread scenarios of self-defined paging model and dynamic area
State calculates the print range of every page.Referring to Fig. 7.
By taking Fig. 7 table sample as an example：In design state, our self-defined paging is as a result, the printing fixed area the 1, the 2nd of page 1
Page printing dynamic area, page 3 prints fixed area 2. but in data state, and dynamic area may be expanded to according to the size of data volume
Tens rows, hundreds of rows even thousands of rows, in this case, dynamic area may need sequentially to be assigned to be printed on multipage, fixed
The page number in area 2 necessarily can also put off backward.
The dynamic page of data state is adjusted, it is necessary to two steps.
1st step is to extend information to collect the dynamic area of data state, calculates growth of the print area in height and width
Situation.Process is as follows：
(1) take the page in the corresponding region of design state, be set to region 1；
(2) in accordance with the order from top to bottom, each cell of the region rightmost side is traveled through successively, obtains data state
Actual position, obtains the maximum column in ergodic process；
(3) according to order from left to right, each cell of the region bottom is traveled through successively, obtains data state
Actual position, obtains the maximum row in ergodic process；
(4) the data state position of the upper left cell lattice of region 1 is taken
(5) cell location for taking the maximum ranks generated by (2) and (3) to navigate to
(6) it is starting to make the cell that (4) are generated, and the cell of (5) generation is constructed under data state, currently to terminate
The data state region of page, is set to region 2
(7) height and width in comparison domain 1 and region 2, if equal, illustrates that this page need not handle the expansion of dynamic area
Exhibition situation；If illustrating the extension due to dynamic area, the width or height of this page are increased.
2nd step is the growth pattern according to wide and height, and necessary fractionation is done in the paging that those are extended.
In this step, if width and height do not change, scope of the current page in design state is directly returned to, otherwise, it is necessary to root
According to factors such as paper sizes, calculate whether current page needs extension to be printed on multipage, and return to the multipage result after extension.
Exemplified by highly changing, the paging flow calculated after the extension of current page is as shown in Figure 8.
By Fig. 9 fixed areas enumerated and dynamic area interlock printing paging exemplified by, it is assumed that in data state, dynamic area is expanded to
100 rows, then following change can dynamically occur for the line index in its paging model：
Specific embodiment：
