ExcelTemplate Grouping and Nesting allows users to bind flat data to a specially formatted spreadsheet with the data being displayed in a grouped or nested format. Here are some data markers and a data marker modifier that are used in this demo:
%%group //
Signals the beginning of the grouping formatting rows. The grouping will be performed on the data field in this column and all rows below this row and above the %%endgroup row will be included in the grouping formatting. Use multiple tiered %%group and %%endgroup tags on separate columns to perform nested grouping.
%%endgroup //
Signals the end of the grouping formatting rows. This data marker should be placed in the same column as the original %%group tag. Use multiple tiered %%group and %%endgroup tags on separate columns to perform nested grouping.
%%header //
Signals the beginning of the header rows for a given group. All the rows between this row and the data markers row are repeated above the data rows for each group. In this sample, the header contains a single row with the values of the individual group categories.
%%footer
Signals the beginning of the footer rows for a given group. All the rows between this row and the %%endgroup row are repeated below the data rows for each group. In this sample, the footer row contains a subtotal row for the groups.
%%value() //
Used to reference a data marker from the header or footer rows. In the sample, this is used to place the value of the individual groups in the header for each group.
(hide) //
Used to hide a data marker value. In this sample, the data marker for the grouping categories has a hide modifier in order to keep the repeated values from showing in the resulting spreadsheet. The values are instead shown in the header row using a %%value() data marker.
