# PDF Datasheet Generator - Implementation Summary
|
|
|
|
## Task Requirements
|
|
|
|
✅ **Include ALL Excel data** - Not just a subset
|
|
✅ **One table per voltage rating** (10kV, 20kV, 30kV, etc.)
|
|
✅ **Use specific compact headers**: DI, RI, Wi, Ibl, Ibe, Ik, Wm, Rbv, Ø, Fzv, Al, Cu, G
|
|
✅ **Columns span full width**
|
|
✅ **Handle missing data**
|
|
✅ **Keep design clean**
|
|
|

|
|
|
|
## Key Changes Made
|
|
|
|
### 1. Complete Excel Data Extraction
|
|
|
|
**Before**: Only 11-13 columns matched for NA2XSFL2Y
|
|
**After**: All 42+ Excel columns mapped
|
|
|
|
```typescript
|
|
// Added 31 new column mappings
|
|
const columnMapping = {
|
|
// Original 11
|
|
'diameter over insulation': { header: 'DI', unit: 'mm', key: 'DI' },
|
|
'dc resistance at 20 °C': { header: 'RI', unit: 'Ohm/km', key: 'RI' },
|
|
// ... 10 more
|
|
|
|
// NEW: 31 additional columns
|
|
'conductor diameter (approx.)': { header: 'Conductor diameter', unit: 'mm', key: 'cond_diam' },
|
|
'capacitance (approx.)': { header: 'Capacitance', unit: 'uF/km', key: 'cap' },
|
|
'inductance, trefoil (approx.)': { header: 'Inductance trefoil', unit: 'mH/km', key: 'ind_trefoil' },
|
|
// ... 28 more
|
|
};
|
|
```
|
|
|
|
### 2. Smart Data Separation
|
|
|
|
**Problem**: All columns were included in tables, even constants
|
|
**Solution**: Three-way separation
|
|
|
|
```typescript
|
|
// 1. Global constants (same for ALL voltage groups)
|
|
// → Moved to Technical Data section
|
|
const globalConstants = new Set();
|
|
for (const column of matchedColumns) {
|
|
const values = rows.map(r => r[column]);
|
|
const unique = new Set(values.map(v => v.toLowerCase()));
|
|
if (unique.size === 1) {
|
|
globalConstants.add(column); // e.g., Conductor: Aluminum
|
|
}
|
|
}
|
|
|
|
// 2. Voltage-specific constants (same within voltage)
|
|
// → Moved to meta items above table
|
|
const voltageConstants = new Set();
|
|
for (const column of variableColumns) {
|
|
const values = voltageGroup.map(r => r[column]);
|
|
const unique = new Set(values.map(v => v.toLowerCase()));
|
|
if (unique.size === 1) {
|
|
voltageConstants.add(column); // e.g., Wi=3.4 for 6/10kV
|
|
}
|
|
}
|
|
|
|
// 3. Variable columns (different per cross-section)
|
|
// → Only these go in tables
|
|
const variableColumns = allColumns.filter(c =>
|
|
!globalConstants.has(c) && !voltageConstants.has(c)
|
|
);
|
|
```
|
|
|
|
### 3. Column Prioritization
|
|
|
|
**Before**: Random order in tables
|
|
**After**: Strict priority system
|
|
|
|
```typescript
|
|
function prioritizeColumnsForDenseTable(columns) {
|
|
const requiredOrder = ['DI', 'RI', 'Wi', 'Ibl', 'Ibe', 'Ik', 'Wm', 'Rbv', 'Ø', 'Fzv', 'Al', 'Cu', 'G'];
|
|
|
|
// 1. Always show required headers first (in exact order)
|
|
const required = requiredOrder
|
|
.map(key => columns.find(c => c.key === key))
|
|
.filter(Boolean);
|
|
|
|
// 2. Then show additional technical columns
|
|
const additional = columns.filter(c => !requiredOrder.includes(c.key));
|
|
|
|
return [...required, ...additional];
|
|
}
|
|
```
|
|
|
|
### 4. Header Abbreviations
|
|
|
|
**Before**: Only 13 headers handled
|
|
**After**: All 42+ columns have abbreviations
|
|
|
|
```typescript
|
|
function headerLabelFor(key) {
|
|
// Required 13
|
|
if (key === 'DI') return 'DI';
|
|
if (key === 'RI') return 'RI';
|
|
if (key === 'Wi') return 'Wi';
|
|
// ... 10 more
|
|
|
|
// NEW: Additional columns
|
|
if (key === 'cond_diam') return 'Ø Leiter';
|
|
if (key === 'cap') return 'C';
|
|
if (key === 'ind_trefoil') return 'L';
|
|
if (key === 'heat_trefoil') return 'τ';
|
|
if (key === 'max_op_temp') return 'Tmax';
|
|
// ... 30+ more
|
|
}
|
|
```
|

## Data Flow
|
|
|
|
### For Each Product
|
|
|
|
1. **Load Excel Rows** (all 4 files)
|
|
2. **Match Product** by name/slug/SKU
|
|
3. **Group by Voltage Rating** (6/10, 12/20, 18/30 kV, etc.)
|
|
4. **Separate Columns**:
|
|
- **Global Constants** → Technical Data section
|
|
- **Voltage Constants** → Meta items
|
|
- **Variable Data** → Tables
|
|
5. **Render PDF**:
|
|
```
