cell spann/merge that consider other columns

[lhegenba]

Description
The possibility to add dependencies on when to cell span/merge
A column X should only spann/merge, if column Y and Z have also span/merge there

Example of what we like to do

How it works in ag grid

{headerName: 'Work Center',field: 'workcenter',editable: true,spanRows: customSpanFuncMaterialOperaionNo,...agGridTextColumnConfig,},
...const customSpanFuncMaterialOperaionNo = ({ nodeA, nodeB, column }: SpanRowsParams) => { 
 if (!nodeA || !nodeB) return false;const colId = column.getColId();return (nodeA.data['material'] === nodeB.data['material'] &&nodeA.data['operationNo'] === nodeB.data['operationNo'] &&nodeA.data[colId] === nodeB.data[colId]);};

It seems you are describing pro version span/merge feature, is that so or there is something more?

Hello @revolist,

I think what @lhegenba means is that more granular control is needed. Instead of automatically merging everything, it should be possible to define how merging works.

Example:
Column 2 is without group mergin, it has merge:true set.
Column 4,5,6,7,9,10,11 are in a kinda like merge group and for example the column 6 is the leading column

This means that all other columns in the group follow the merge behavior of Column 6. Even if the next row contains the same value as above in those other columns, they will only merge as far as Column 6 merges.

Implemented in the Pro repository: https://github.com/revolist/revogrid-pro/pull/377

The PR adds dependency-based SameValueMergePlugin boundaries with mergeGroup, mergeLeader, and mergeDependsOn, so follower columns can visually merge only within a leader column's run while merge: true remains backward compatible.
