文件夹下Excel内容搜索(Python)

基于 PyQt5 和 xlrd 库实现

https://github.com/moneypi/SearchExcel.git

界面模仿 Everything 实现，无需点击搜索按钮，搜索框输入内容会自动开始搜索，

当搜索框为空时不进行搜索

代码如下：

import sys, os
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QAbstractItemView, QTableWidgetItem, QTableWidget, \
    QFileDialog
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot, QCoreApplication, Qt
from PyQt5.Qt import QLineEdit
import xlrd

_translate = QCoreApplication.translate


class App(QWidget):
    def __init__(self):
        super().__init__()
        self.title = 'SearchExcel '

        self.pathTextBox = QLineEdit(self)
        self.setWindowTitle(self.title)

        self.pathTextBox.move(20, 20)

        # create searchTextBox
        self.searchTextBox = QLineEdit(self)
        self.searchTextBox.move(20, 80)
        self.searchTextBox.textChanged.connect(self.onTextChange)

        # Create a openPathButton in the window
        self.openPathButton = QPushButton('打开文件夹', self)

        self.tableWidget = QTableWidget(self)

        self.tableWidget.setObjectName("tableWidget")
        self.tableWidget.setColumnCount(5)
        self.tableWidget.setRowCount(0)

        for i in range(3):
            item = QTableWidgetItem()
            self.tableWidget.setVerticalHeaderItem(i, item)

        for i in range(5):
            item = QTableWidgetItem()
            item.setTextAlignment(Qt.AlignCenter)
            self.tableWidget.setHorizontalHeaderItem(i, item)
        self.tableWidget.horizontalHeader().setCascadingSectionResizes(True)

        item = self.tableWidget.horizontalHeaderItem(0)
        item.setText(_translate("widget", "文件名"))
        item = self.tableWidget.horizontalHeaderItem(1)
        item.setText(_translate("widget", "Sheet"))
        item = self.tableWidget.horizontalHeaderItem(2)
        item.setText(_translate("widget", "行"))
        item = self.tableWidget.horizontalHeaderItem(3)

        self.tableWidget.setEditTriggers(QAbstractItemView.NoEditTriggers)

        # connect openPathButton to function on_click
        self.openPathButton.clicked.connect(self.on_click)
        self.showMaximized()

    @pyqtSlot()
    def on_click(self):
        self.pathTextBox.setText(QFileDialog.getExistingDirectory(None, "请选择文件夹路径"))

    def resizeEvent(self, a0):
        self.pathTextBox.resize(self.width() * 0.8, 40)
        self.openPathButton.move(self.width() * 0.85, 20)

已知bug

对于日期格式搜索无法搜索，如格式为 

2018/5/31

的，没有进行正确的字符串转换，所以无法搜索
