+# To AI Agent: Implement Clickable Google Maps Hyperlinks in PDF Export Table
+
+## 1. Context & Feature Objective
+We are upgrading the PDF export functionality within the Yotrip Travel Planner application. Currently, the PDF generates a static table containing location names, addresses, and coordinates.
+**Objective:** Automatically turn every location row inside the PDF table into an interactive, clickable hyperlink. When a user clicks on the location cell in the generated PDF document, it must immediately open a browser tab navigating directly to that exact location on Google Maps.
+
+---
+
+## 2. Technical Architecture & Data Strategy
+
+Because `jspdf-autotable` draws text onto a canvas layout, raw HTML tags like `<a>` will fail. We must implement a two-step rendering lifecycle:
+1. **Extraction & Styling State:** During the data loop, verify coordinates or address data. Generate a standard universal Google Maps search URL, save it into a coordinate-tracking index object, and transform the raw text cell into a styled cell object (Yale Blue text `#28536b` to mimic an online link).
+2. **Link Injection Layer:** Utilize the `didDrawCell` hook callback inside the `doc.autoTable` configuration to position a native invisible link window (`doc.link()`) precisely over the drawn dimensions of that specific location cell.
+
+---
+
+## 3. Code Refactoring Specification
+
+### Step 1: Update Data Preparation Loop
+Locate the loop processing `currentTour.legs` inside your PDF generation code block. Initialize a temporary lookup map array named `pdfMapLinks` and refactor the item distribution logic as follows:
+
+```typescript
+// Initialize an index mapping registry for hyperlinks before the loop execution
+const pdfMapLinks: { [key: number]: string } = {};
+
+if (currentTour?.legs && currentTour.legs.length > 0) {
+  currentTour.legs.forEach((leg: any, legIdx: number) => {
+    const legName = leg.note || `Chặng ${legIdx + 1}`;
+    const legLocations = (leg.locations || []).filter((loc: any) =>
+      loc && (loc.plannedStart || loc.plannedEnd || loc.name)
+    );
+
+    const startRow = globalRowIndex;
+
+    if (legLocations.length > 0) {
+      legRowRanges[leg.id] = { start: startRow, count: legLocations.length };
+
+      legLocations.forEach((loc: any, locIdx: number) => {
+        const isStartPoint = loc.plannedStart && new Date(loc.plannedStart).getTime() === 0;
+        const timeSource = isStartPoint ? loc.plannedEnd : loc.plannedStart;
+        const timeStr = timeSource ? formatDateTime(timeSource) : '';
+
+        const locName = loc.name || '';
+        const addressStr = loc.address || '';
+        const coordStr = loc.latitude && loc.longitude
+          ? `\n${loc.latitude}, ${loc.longitude}`
+          : '';
+        const locationText = [locName, addressStr, coordStr].filter(Boolean).join('\n');
+        const noteText = loc.note || '';
+
+        // 1. Generate standard universal Google Maps URL query pattern
+        let mapUrl = '';
+        if (loc.latitude && loc.longitude) {
+          // Absolute Precision using GPS coordinates
+          mapUrl = `https://www.google.com/maps/search/?api=1&query=${loc.latitude},${loc.longitude}`;
+        } else if (addressStr || locName) {
+          // Text-search query fallback if GPS coordinates are missing
+          mapUrl = `https://www.google.com/maps/search/?api=1&query=${encodeURIComponent(addressStr || locName)}`;
+        }
+
+        // 2. Register current row array position to map lookup index
+        const currentRowPosition = tableRows.length;
+        if (mapUrl) {
+          pdfMapLinks[currentRowPosition] = mapUrl;
+        }
+
+        // 3. Convert raw string into custom styled autoTable Cell configuration object
+        const locationCellObj = {
+          content: locationText,
+          // Apply custom link colors matching theme style #28536b (Yale Blue)
+          styles: mapUrl ? { textColor: [40, 83, 107], fontStyle: 'bold' as const } : {}
+        };
+
+        tableRows.push([
+          stt++,
+          timeStr,
+          locIdx === 0 ? legName : '',
+          locationCellObj, // Injected as cell structure object
+          noteText
+        ]);
+        globalRowIndex++;
+      });
+    } else {
+      legRowRanges[leg.id] = { start: startRow, count: 1 };
+      tableRows.push([
+        stt++,
+        '',
+        legName,
+        'Chưa có địa điểm trong chặng này',
+        ''
+      ]);
+      globalRowIndex++;
+    }
+  });
+}
+
+### Step 2: Inject Coordinate-Based Overlay inside doc.autoTable
+Locate the core configuration module block where doc.autoTable({}) is invoked. Inject the didDrawCell event engine to deploy the link bounds:
+
+doc.autoTable({
+  head: [['STT', 'Thời gian', 'Chặng', 'Địa điểm', 'Ghi chú']],
+  body: tableRows,
+  theme: 'grid',
+  
+  // HOOK HANDLER: Overlays active coordinate zones on top of native cells after writing
+  didDrawCell: (data: any) => {
+    // Target explicitly: body section only + column index 3 (Location Column)
+    if (data.section === 'body' && data.column.index === 3) {
+      const activeRowIndex = data.row.index;
+      const targetMapUrl = pdfMapLinks[activeRowIndex];
+      
+      if (targetMapUrl) {
+        // Build active link container utilizing jsPDF coordinates framework
+        data.doc.link(
+          data.cell.x, 
+          data.cell.y, 
+          data.cell.width, 
+          data.cell.height, 
+          { url: targetMapUrl }
+        );
+      }
+    }
+  },
+  styles: { font: 'Roboto' } // Retain existing styling structure
+});
+
+## 4. Quality Control & Acceptance Criteria
+[ ] Visual Differentiation: Location text cells containing map URLs must render cleanly in bold dark-blue ([40, 83, 107]) while empty state texts stay muted.
+
+[ ] Coordinate Precision: Clicking a location card possessing explicit coordinates (latitude, longitude) must directly map to those absolute markers instead of doing an inaccurate keyword address query.
+
+[ ] Boundary Accuracy: The click targets must fit perfectly inside the grid cell borders. Clicking near the edges of column 3 must register properly, while clicking column 2 (Leg name) or column 4 (Notes) must remain non-reactive.
