table控件需要显示7列数据，行数不确定。
只显示一行数据时，界面正常，按钮可起作用，table列可左右拖动。
显示多行数据时，比如除标题行外，数据行3行及以上时，按按钮来回切换该页面和其他页面，都正常，数据刷新也正常。但是左右拖动或上下拖动table列或行时，有很大几率界面卡死，但是table里的数据还能正常刷新。
请教，这是哪里的问题？

{
lv_init();
lv_port_disp_init();
lv_port_indev_init();

打开了lvgl的帧率及cpu占用率显示功能，内存占用没显示出来，可能和用了malloc有关。
以下提到的界面卡死，只是lvgl界面卡死，不能按及拖动，但是lvgl还能刷新帧率及cpu占用率，rtt的其他线程也正常。
复制了官方table例程：
https://lvgl.100ask.net/8.2/widgets/core/table.html#
例程是2列7行，运行后大部分情况下正常，有很小概率出现界面卡死。
改成4列7行，界面卡死概率更大了。
行列互换，改成7列，然后添加若干行，很容易出现界面卡死。
不拖动，只按压table的表格项，有时候会出现画面跳动以下，感觉像是触控数据出了问题。
void test_ui_init(void)
{
static lv_style_t fontDefault;
lv_style_init(&fontDefault);
lv_style_set_text_font(&fontDefault, &lv_font_montserrat_30);
lv_obj_t * table = lv_table_create(lv_scr_act());
// lv_obj_add_style(table, &fontDefault, 0);
lv_obj_set_size(table, 700, 400);
lv_table_set_cell_value(table, 0, 0, "Name");
lv_table_set_cell_value(table, 1, 0, "Apple");
lv_table_set_cell_value(table, 2, 0, "Banana");
lv_table_set_cell_value(table, 3, 0, "Lemon");
lv_table_set_cell_value(table, 4, 0, "Grape");
lv_table_set_cell_value(table, 5, 0, "Melon");
lv_table_set_cell_value(table, 6, 0, "Peach");
lv_table_set_cell_value(table, 7, 0, "Nuts");
lv_table_set_cell_value(table, 0, 1, "Price");
lv_table_set_cell_value(table, 1, 1, "$7");

// lv_table_set_cell_value(table, 2, 3, "$4");

// lv_table_set_cell_value(table, 6, 3, "$1");
// lv_table_set_cell_value(table, 7, 3, "$9");
// lv_obj_set_height(table, 200);
lv_obj_center(table);
lv_obj_add_event_cb(table, draw_part_event_cb, LV_EVENT_DRAW_PART_BEGIN, NULL);
}打开了lvgl的日值功能，有时候会出现这种警告：
[Warn] (60.346, +10) indev_pointer_proc: X is 809 which is greater than hor. res (in lv_indev.c line #362)
[Warn] (60.356, +10) indev_pointer_proc: X is 809 which is greater than hor. res (in lv_indev.c line #362)

[Warn] (60.426, +10) indev_pointer_proc: X is 809 which is greater than hor. res (in lv_indev.c line #362)而且，手已经抬起没有再按压，结果还是不停的出现这个警告，再按下屏幕才消失。
不过出现界面卡死时不一定会有这个警告，有这个警告不一定会界面卡死。

lvgl线程优先级是20,touch线程优先级是25,改成19后，问题貌似消失，测试时间还不够长，有待验证，也不清楚修改优先级后会不会有其他影响。
