[Feature Request] Filter and Sort by column in the grid

[bencz]

I would like to use the filter system by column and sorting in the grid

Here, I have a small sample of how to use the ListView Filter:

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <commctrl.h>
#include <string.h>
#include <stdbool.h>

#define WND_CLASS_NAME "CSVVIEW"
#define ID_LISTVIEW 0x8801

char* filename;
HWND hList, hHeader;
static NMLISTVIEW* nmListView;
static NMHEADER* nmHeader;


int rgb(int r, int g, int b) { return r + (g << 8) + (b << 16); }

bool startsWith(const char* pre, const char* str)
{
	size_t lenpre = strlen(pre),
		lenstr = strlen(str);
	return lenstr < lenpre ? false : memcmp(pre, str, lenpre) == 0;
}

void onCreate(HWND hWnd, LPARAM lParam) {
	LVCOLUMN col;
	LVITEM item;
	int iCol, iCount, dwStyle, dwHeaderStyle;
	CREATESTRUCT* lp = (CREATESTRUCT*)lParam;

	char* field;

	memset(&item, 0, sizeof(item));
	hList = CreateWindowEx(0, WC_LISTVIEW, 0, WS_CHILD | WS_VISIBLE | LVS_REPORT, 0, 0, 100, 100, hWnd, (HMENU)ID_LISTVIEW, lp->hInstance, NULL);
	dwStyle = SendMessage(hList, LVM_GETEXTENDEDLISTVIEWSTYLE, 0, 0);
	dwStyle = dwStyle | LVS_EX_CHECKBOXES | LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | LVS_EX_HEADERDRAGDROP | LVS_EX_FLATSB;
	SendMessage(hList, LVM_SETEXTENDEDLISTVIEWSTYLE, 0, dwStyle);
	col.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH | LVCF_SUBITEM;


	nmListView = (NMLISTVIEW*)hList;

	// TEST HEADER

	hHeader = ListView_GetHeader(hList);
	SetWindowLong(hHeader, GWL_ID, ID_LISTVIEW + 1);

	Header_SetFilterChangeTimeout(hHeader, 1000);
	dwHeaderStyle = (GetWindowLongPtr(hHeader, GWL_STYLE) | HDS_FILTERBAR) & ~HDS_BUTTONS;
	SetWindowLong(hHeader, GWL_STYLE, dwHeaderStyle);

	nmHeader = (NMHEADER*)hHeader;
