Column Quickthrough

The most simple definition for a column is a vertical series of cells.

There are 2 roles: Data Column and Meta Column

Data Columns (PblColumn)

• All green cells belong to the column name.
• They all share most of the column definitions (e.g. width).
• They differ based on the column sub-role

There are 3 sub-roles, here in visual order of appearance:

• 1 header cell
• N data cells (in this example, N === 2)
• 1 footer cell

The split is fixed, it will always be 1/N/1.

Each sub-role will have its unique

• Rendering template (more on this later...)
• Role CSS class name (pbl-ngrid-header-cell, pbl-ngrid-cell, pbl-ngrid-footer-cell)
• Column data type (optional)

The CSS classes shared by all sub-roles:

• CSS set in the column definitions definitions (css)
• Identity CSS (pbl-ngrid-column-[Identity])

They all share a logical connection, they work as one unit:

• If we hide the column all 3 are gone.
• If we change the width all 3 will change.
• If we move column all 3 will move together.

A data column is the only column that span over a vertical series of cells.

Meta Columns (PblMetaColumn)

• All skyblue cells are meta columns
• Except the role they share nothing.
• The border color indicates their sub-role: Meta Header, Meta Header Group and Meta Footer

Each sub-role is hosted in a meta row of the same type, having columns from the same sub-role.

The Meta Header Group has it's own class PblColumnGroup , extending PblMetaColumn
