Struct Plugin: Aggregation
Aggregation of structured data is the main purpose of the plugin. Aggregation is done through a simple syntax which will result in a dynamic table listing all pages and associated data matching certain criteria.
The basic syntax looks like this:
---- struct table ---- schema: schema_name cols: %pageid%, other, cols ----
The aggregation-syntax is very similar to that the data plugin. The main difference is, that you have to specify a schema name (or more than one). 
Also note that the width option no longer exists.
The keyword before the colon is a configuration option and the value behind is the actual setting. To make it more fault tolerant often multiple option names are possible. Here is a list of all available options:
| Option(s) | Required? | Description |
|---|---|---|
| schema from | yes | These are the schemas from which you want to display the data. |
| cols select | yes | These are the attributes you want to display. These are the same names you used in the Data Entry part |
| head header headers | no | If specified, these names will be used in the table headers instead of the column names |
| max limit | no | How many rows should be displayed. If more rows are available the table will be made browsable. If not given all matching rows are shown |
| sort order | no | By what column should the table be sorted initially? Prepend a ^ to reverse the sorting |
| filter where filterand and | no | Filter by a column value. You may specify this more than once, multiple filters will be ANDed. |
| filteror or | no | Like filter, but multiple instances will be ORed |
| dynfilters | no | Set to 1 to enable a row of input fields for dynamically filtering the table |
| summarize | no | Set to 1 to calculate sum of columns |
| align | no | List of column alignments. The alignments can be left (l), center (c) or right (r) |
| rownumbers | no | Set to 1 to show row numbers |
When selecting data from multiple schemas wich contain the same field names, you have to prefix them with the schema name:
---- struct table ---- schemas: schema1, schema2 cols: %pageid%, schema1.name, schema2.name ----
You can use aliases to reference schemas to type less. Aliases are separated by a space from the schema name:
---- struct table ---- schemas: schema1 A, schema2 B cols: %pageid%, A.name, B.name ----
