# PDF Datasheet Generator - Final Implementation
## ✅ Task Complete: ALL Requirements Met
### Requirements from User
1.**Include ALL Excel data** - All 42+ columns extracted
2.**One table per voltage rating** - 6/10, 12/20, 18/30 kV, etc.
3.**ALL 13 columns in EVERY table** - Even if empty
4.**Specific headers**: DI, RI, Wi, Ibl, Ibe, Ik, Wm, Rbv, Ø, Fzv, Al, Cu, G
5.**Full-width columns** - Tables span page width
6.**Handle missing data** - Empty columns shown
7.**Clean design** - Professional industrial layout

## Implementation Summary
### Key Changes Made
#### 1. Complete Excel Data Extraction (Lines 203-283)
```typescript
const columnMapping = {
// 13 Required Headers
'DI': { header: 'DI', unit: 'mm', key: 'DI' },
'RI': { header: 'RI', unit: 'Ohm/km', key: 'RI' },
'Wi': { header: 'Wi', unit: 'mm', key: 'Wi' },
'Ibl': { header: 'Ibl', unit: 'A', key: 'Ibl' },
'Ibe': { header: 'Ibe', unit: 'A', key: 'Ibe' },
'Ik': { header: 'Ik', unit: 'kA', key: 'Ik' },
'Wm': { header: 'Wm', unit: 'mm', key: 'Wm' },
'Rbv': { header: 'Rbv', unit: 'mm', key: 'Rbv' },
'Ø': { header: 'Ø', unit: 'mm', key: 'Ø' },
'Fzv': { header: 'Fzv', unit: 'N', key: 'Fzv' },
'Al': { header: 'Al', unit: '', key: 'Al' },
'Cu': { header: 'Cu', unit: '', key: 'Cu' },
'G': { header: 'G', unit: 'kg/km', key: 'G' },
// 31 Additional Columns (for complete data)
'conductor diameter': { header: 'Conductor diameter', unit: 'mm', key: 'cond_diam' },
'capacitance': { header: 'Capacitance', unit: 'uF/km', key: 'cap' },
// ... 29 more
};
```
#### 2. Smart Data Separation (Lines 327-447)
```typescript
// Global constants (same for all voltages) → Technical Data
const globalConstantColumns = new Set<string>();
for (const { excelKey, mapping } of matchedColumns) {
const values = rows.map(r => normalizeValue(String(r?.[excelKey] ?? ''))).filter(Boolean);
const unique = Array.from(new Set(values.map(v => v.toLowerCase())));
if (unique.length === 1 && values.length > 0) {
globalConstantColumns.add(excelKey);
technicalItems.push({ label: mapping.header, value: values[0] });
}
}
// Per voltage group
for (const [voltage, indices] of byVoltage) {
// Voltage-specific constants → Meta items
const voltageConstants = new Set<string>();
for (const col of allColumns) {
if (globalConstantColumns.has(col)) continue;
const values = indices.map(idx => normalizeValue(String(rows[idx]?.[col] ?? ''))).filter(Boolean);
const unique = Array.from(new Set(values.map(v => v.toLowerCase())));
if (unique.size === 1) {
voltageConstants.add(col);
metaItems.push({ label: mapping.header, value: values[0] });
}
}
// Variable columns → Tables (BUT: ALL 13 required columns always included)
const requiredKeys = ['DI', 'RI', 'Wi', 'Ibl', 'Ibe', 'Ik', 'Wm', 'Rbv', 'Ø', 'Fzv', 'Al', 'Cu', 'G'];
const columns = requiredKeys.map(key => {
const matched = tableColumns.find(c => c.mapping.key === key);
if (matched) {
// Has data
return {
key: matched.mapping.key,
label: `${matched.mapping.header} [${matched.mapping.unit}]`,
get: (rowIndex: number) => { /* ... */ }
};
} else {
// Empty column
return {
key: key,
label: `${headerLabelFor(key)} []`,
get: () => ''
};
}
});
}
```
#### 3. Helper Function (Lines 285-298)
```typescript
function headerLabelFor(key: string): string {
const labels: Record<string, string> = {
'DI': 'DI', 'RI': 'RI', 'Wi': 'Wi', 'Ibl': 'Ibl', 'Ibe': 'Ibe',
'Ik': 'Ik', 'Wm': 'Wm', 'Rbv': 'Rbv', 'Ø': 'Ø', 'Fzv': 'Fzv',
'Al': 'Al', 'Cu': 'Cu', 'G': 'G',
};
return labels[key] || key;
}
```
